Exposing `asUintN()` as a "standard library function" allows [interop with asm.js](https://github.com/tc39/proposal-bigint/blob/master/ADVANCED.mdx#dont-break-asmjs). diff --git a/documentation/versioned_docs/version-1.0.0/globals/Math/imul.mdx b/documentation/versioned_docs/version-1.0.0/globals/Math/imul.mdx deleted file mode 100644 index de22ddc20c..0000000000 --- a/documentation/versioned_docs/version-1.0.0/globals/Math/imul.mdx +++ /dev/null @@ -1,35 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Math.imul() - -The **`Math.imul()`** function returns the result of the C-like 32-bit multiplication of the two parameters. - - -## Syntax - -```js -Math.imul(a, b) -``` - -### Parameters - -- `a` - - : First number. -- `b` - - : Second number. - -### Return value - -The result of the C-like 32-bit multiplication of the given arguments. - -## Description - -`Math.imul()` allows for 32-bit integer multiplication with C-like semantics.

The `revoke` function also detaches `target` and `handler` from the `proxy`, so if `target` is not referenced elsewhere, it will also be eligible for garbage collection, even when its proxy is still alive, since there's no longer a way to meaningfully interact with the target object. - -Letting users interact with an object through a revocable proxy allows you to [control the lifetime](https://developer.mozilla.org/docs/Web/JavaScript/Memory_Management) of the object exposed to the user — you can make the object garbage-collectable even when the user is still holding a reference to its proxy. diff --git a/documentation/versioned_docs/version-1.0.0/globals/ReadableStream/prototype/getReader.mdx b/documentation/versioned_docs/version-1.0.0/globals/ReadableStream/prototype/getReader.mdx deleted file mode 100644 index 9c490b51e9..0000000000 --- a/documentation/versioned_docs/version-1.0.0/globals/ReadableStream/prototype/getReader.mdx +++ /dev/null @@ -1,42 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# ReadableStream.getReader() - -The **`getReader()`** method of the `ReadableStream` interface creates a reader and locks the stream to it. -While the stream is locked, no other reader can be acquired until this one is released. - -## Syntax - -```js -getReader() -getReader(options) -``` - -### Parameters - -- `options` _**optional**_ - - - : An object containing the following properties: - - - `mode` _**optional**_ - - - : An property that specifies the type of reader to create. - Values can be: - - - `"byob"`, which results in a `ReadableStreamBYOBReader` being created that can read readable byte streams (streams that support zero-copy transfer from an underlying byte source to the reader when internal stream buffers are empty). - - `undefined` (or not specified at all — this is the default), which results in a `ReadableStreamDefaultReader` being created that can read individual chunks from a stream. - -### Return value - -A `ReadableStreamDefaultReader` or `ReadableStreamBYOBReader` object instance, depending on the `mode` value. - -### Exceptions - -- `RangeError` - - : Thrown if the provided mode value is not `"byob"` or `undefined`. -- `TypeError` - - : Thrown if the stream you are trying to create a reader for is already locked, or not a `ReadableStream`. \ No newline at end of file diff --git a/documentation/versioned_docs/version-1.0.0/globals/Request/Request.mdx b/documentation/versioned_docs/version-1.0.0/globals/Request/Request.mdx deleted file mode 100644 index 7e60acdf8a..0000000000 --- a/documentation/versioned_docs/version-1.0.0/globals/Request/Request.mdx +++ /dev/null @@ -1,45 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Request() - -The **`Request()`** constructor creates a new -`Request` object. - -## Syntax - -```js -new Request(input) -new Request(input, options) -``` - -### Parameters - -- `input` - - - : Defines the resource that you wish to fetch.

You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. - -If any parameter overflows its defined bounds, it "carries over". For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M. June 20th, 2020. - -Similarly, if any parameter underflows, it "borrows" from the higher positions. For example, `new Date(2020, 5, 0)` will return May 31st, 2020. - -- `year` - - : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year. See the [example](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date#interpretation_of_two-digit_years). -- `monthIndex` - - : Integer value representing the month, beginning with `0` for January to `11` for December. -- `day` _**optional**_ - - : Integer value representing the day of the month.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result. This constraint ensures that a proper serialization (and, very likely, its accompanying deserialization) behavior is always explicitly provided by the user. -- [`undefined`](../../globals/undefined.mdx), `Function`, and `Symbol` values are not valid JSON values. If any such values are encountered during conversion, they are either omitted (when found in an object) or changed to [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null) (when found in an array). `JSON.stringify()` can return `undefined` when passing in "pure" values like `JSON.stringify(() => {})` or `JSON.stringify(undefined)`. -- The numbers [`Infinity`](../../globals/Infinity.mdx) and [`NaN`](../../globals/NaN.mdx), as well as the value [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null), are all considered `null`.

Instead of the object being serialized, the value returned by the `toJSON()` method when called will be serialized. `JSON.stringify()` calls `toJSON` with one parameter, the `key`, which has the same semantic as the `key` parameter of the [`replacer`](#the_replacer_parameter) function: - - - if this object is a property value, the property name - - if it is in an array, the index in the array, as a string - - if `JSON.stringify()` was directly called on this object, an empty string - - `Date` objects implement the [`toJSON()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toJSON) method which returns a string (the same as [`date.toISOString()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)). Thus, they will be stringified as strings. - - - Only [enumerable own properties](https://developer.mozilla.org/docs/Web/JavaScript/Enumerability_and_ownership_of_properties) are visited. This means [Map](../../globals/Map/Map.mdx), [Set](../../globals/Set/Set.mdx), etc. will become `"{}"`. You can use the [`replacer`](#the_replacer_parameter) parameter to serialize them to something more useful. - - Properties are visited using the same algorithm as [`Object.keys()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object/keys), which has a well-defined order and is stable across implementations. For example, `JSON.stringify` on the same object will always produce the same string, and `JSON.parse(JSON.stringify(obj))` would produce an object with the same key ordering as the original (assuming the object is completely JSON-serializable). - -### The replacer parameter - -The `replacer` parameter can be either a function or an array. - -As an array, its elements indicate the names of the properties in the object that should be included in the resulting JSON string.

It is then called for each property on the object or array being stringified. Array indices will be provided in its string form as `key`. The current property value will be replaced with the `replacer`'s return value for stringification. This means: - -- If you return a number, string, boolean, or `null`, that value is directly serialized and used as the property's value. (Returning a BigInt will throw as well.) -- If you return a `Function`, `Symbol`, or [`undefined`](../../globals/undefined.mdx), the property is not included in the output. -- If you return any other object, the object is recursively stringified, calling the `replacer` function on each property. - -> **Note:** When parsing JSON generated with `replacer` functions, you would likely want to use the [`reviver`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#using_the_reviver_parameter) parameter to perform the reverse operation. - -Typically, array elements' index would never shift (even when the element is an invalid value like a function, it will become `null` instead of omitted).

The method will also return `true` for floating point numbers that can be represented as integer. It will always return `false` if the value is not a number. - -Note that some number literals, while looking like non-integers, actually represent integers — due to the precision limit of ECMAScript floating-point number encoding (IEEE-754). For example, `5.0000000000000001` only differs from `5` by `1e-16`, which is too small to be represented. (For reference, [`Number.EPSILON`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number/EPSILON) stores the distance between 1 and the next representable floating-point number greater than 1, and that is about `2.22e-16`.) Therefore, `5.0000000000000001` will be represented with the same encoding as `5`, thus making `Number.isInteger(5.0000000000000001)` return `true`. - -In a similar sense, numbers around the magnitude of [`Number.MAX_SAFE_INTEGER`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number/MAX_SAFE_INTEGER) will suffer from loss of precision and make `Number.isInteger` return `true` even when it's not an integer. (The actual threshold varies based on how many bits are needed to represent the decimal — for example, `Number.isInteger(4500000000000000.1)` is `true`, but `Number.isInteger(4500000000000000.5)` is `false`.) diff --git a/documentation/versioned_docs/version-1.1.0/globals/Number/isNaN.mdx b/documentation/versioned_docs/version-1.1.0/globals/Number/isNaN.mdx deleted file mode 100644 index 2244aabc9d..0000000000 --- a/documentation/versioned_docs/version-1.1.0/globals/Number/isNaN.mdx +++ /dev/null @@ -1,32 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Number.isNaN() - -The **`Number.isNaN()`** method determines whether the passed value is the number value [`NaN`](../../globals/NaN.mdx), and returns `false` if the input is not of the Number type.

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously).

The `then` method is called asynchronously, so that the promise will never be instantly resolved if a thenable is passed. - -Because `resolve` is called again with whatever `thenable.then()` passes to it as `value`, the resolver function is able to flatten nested thenables, where a thenable calls its `onFulfilled` handler with another thenable.

You are advised to make your custom `@@unscopables` property have `null` as its prototype, like [`Array.prototype[Symbol.unscopables]`](../../globals/Array/prototype/@@unscopables.mdx) does. diff --git a/documentation/versioned_docs/version-1.1.0/globals/SyntaxError/SyntaxError.mdx b/documentation/versioned_docs/version-1.1.0/globals/SyntaxError/SyntaxError.mdx deleted file mode 100644 index 594cd84d28..0000000000 --- a/documentation/versioned_docs/version-1.1.0/globals/SyntaxError/SyntaxError.mdx +++ /dev/null @@ -1,38 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# SyntaxError - -The **`SyntaxError`** constructor creates a new error object -that represents an error when trying to interpret syntactically invalid code. - -## Syntax - -```js -new SyntaxError() -new SyntaxError(message) -new SyntaxError(message, options) -new SyntaxError(message, fileName) -new SyntaxError(message, fileName, lineNumber) - -SyntaxError() -SyntaxError(message) -SyntaxError(message, options) -SyntaxError(message, fileName) -SyntaxError(message, fileName, lineNumber) -``` - -> **Note:** `SyntaxError()` can be called with or without `new`.

It runs a "reducer" callback function over all elements in the array, in ascending-index order, and accumulates them into a single value. Every time, the return value of `callbackFn` is passed into `callbackFn` again on next invocation as `accumulator`. The final value of `accumulator` (which is the value returned from `callbackFn` on the final iteration of the array) becomes the return value of `reduce()`. - -`callbackFn` is invoked only for array indexes which have assigned values. It is not invoked for empty slots in sparse arrays. - -Unlike other [iterative methods](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Array#iterative_methods), `reduce()` does not accept a `thisArg` argument. `callbackFn` is always called with `undefined` as `this`, which gets substituted with `globalThis` if `callbackFn` is non-strict. - -`reduce()` is a central concept in [functional programming](https://en.wikipedia.org/wiki/Functional_programming), where it's not possible to mutate any value, so in order to accumulate all values in an array, one must return a new accumulator value on every iteration. This convention propagates to JavaScript's `reduce()`: you should use [spreading](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Spread_syntax) or other copying methods where possible to create new arrays and objects as the accumulator, rather than mutating the existing one. If you decided to mutate the accumulator instead of copying it, remember to still return the modified object in the callback, or the next iteration will receive undefined. - -`reduce()` does not mutate the array on which it is called, but the function provided as `callbackFn` can. Note, however, that the length of the array is saved _before_ the first invocation of `callbackFn`. Therefore: - -- `callbackFn` will not visit any elements added beyond the array's initial length when the call to `reduce()` began. -- Changes to already-visited indexes do not cause `callbackFn` to be invoked on them again. -- If an existing, yet-unvisited element of the array is changed by `callbackFn`, its value passed to the `callbackFn` will be the value at the time that element gets visited.

If code becomes clearer when using other array methods, developers must weigh the readability tradeoff against the other benefits of using `reduce()`. In cases where `reduce()` is the best choice, documentation and semantic variable naming can help mitigate readability drawbacks. - -### Edge cases - -If the array only has one element (regardless of position) and no `initialValue` is provided, or if `initialValue` is provided but the array is empty, the solo value will be returned _without_ calling `callbackFn`. - -If `initialValue` is provided and the array is not empty, then the reduce method will always invoke the callback function starting at index 0. - -If `initialValue` is not provided then the reduce method will act differently for arrays with length larger than 1, equal to 1 and 0, as shown in the following example: - -```js -const getMax = (a, b) => Math.max(a, b); - -// callback is invoked for each element in the array starting at index 0 -[1, 100].reduce(getMax, 50); // 100 -[50].reduce(getMax, 10); // 50 - -// callback is invoked once for element at index 1 -[1, 100].reduce(getMax); // 100 - -// callback is not invoked -[50].reduce(getMax); // 50 -[].reduce(getMax, 1); // 1 - -[].reduce(getMax); // TypeError -``` diff --git a/documentation/versioned_docs/version-1.10.0/globals/Array/prototype/reduceRight.mdx b/documentation/versioned_docs/version-1.10.0/globals/Array/prototype/reduceRight.mdx deleted file mode 100644 index 6c3f91cc44..0000000000 --- a/documentation/versioned_docs/version-1.10.0/globals/Array/prototype/reduceRight.mdx +++ /dev/null @@ -1,79 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Array.prototype.reduceRight() - -The **`reduceRight()`** method applies a function against an -accumulator and each value of the array (from right-to-left) to reduce it to a single -value. - -See also [`Array.prototype.reduce()`](./reduce.mdx) for left-to-right. - -## Syntax - -```js -// Arrow function -reduceRight((accumulator, currentValue) => { /* … */ }) -reduceRight((accumulator, currentValue, index) => { /* … */ }) -reduceRight((accumulator, currentValue, index, array) => { /* … */ }) -reduceRight((accumulator, currentValue, index, array) => { /* … */ }, initialValue) - -// Callback function -reduceRight(callbackFn) -reduceRight(callbackFn, initialValue) - -// Callback reducer function -reduceRight(function (accumulator, currentValue) { /* … */ }) -reduceRight(function (accumulator, currentValue, index) { /* … */ }) -reduceRight(function (accumulator, currentValue, index, array) { /* … */ }) -reduceRight(function (accumulator, currentValue, index, array) { /* … */ }, initialValue) -``` - -### Parameters - -- `callbackFn` - - - : A function to execute for each element in the array.

Keep in mind that most [UNIX Timestamp](https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_16) functions are only accurate to the nearest second. - -#### Date string - -- `dateString` - - - : A string value representing a date, in a format recognized by the [`Date.parse()`](./parse.mdx) method. (The ECMA262 spec specifies a [simplified version of ISO 8601](https://tc39.es/ecma262/#sec-date-time-string-format), but other formats can be implementation-defined, which commonly include [IETF-compliant RFC 2822 timestamps](https://datatracker.ietf.org/doc/html/rfc2822#page-14).) - - > **Note:** When parsing date strings with the `Date` constructor (and `Date.parse`, they are equivalent), always make sure that the input conforms to the ISO 8601 format (`YYYY-MM-DDTHH:mm:ss.sssZ`) — the parsing behavior with other formats is implementation-defined and may not work across all browsers. Support for [RFC 2822](https://datatracker.ietf.org/doc/html/rfc2822) format strings is by convention only. A library can help if many different formats are to be accommodated. - > - > Date-only strings (e.g. `"1970-01-01"`) are treated as UTC, while date-time strings (e.g. `"1970-01-01T12:00"`) are treated as local. You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. - -If any parameter overflows its defined bounds, it "carries over". For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M. June 20th, 2020. - -Similarly, if any parameter underflows, it "borrows" from the higher positions. For example, `new Date(2020, 5, 0)` will return May 31st, 2020. - -- `year` - - : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year. See the [example](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date#interpretation_of_two-digit_years). -- `monthIndex` - - : Integer value representing the month, beginning with `0` for January to `11` for December. -- `day` _**optional**_ - - : Integer value representing the day of the month. The default is `1`. -- `hours` _**optional**_ - - : Integer value between `0` and `23` representing the hour of the day. Defaults to `0`. -- `minutes` _**optional**_ - - : Integer value representing the minute segment of a time. The default is `0` minutes past the hour. -- `seconds` _**optional**_ - - : Integer value representing the second segment of a time. The default is `0` seconds past the minute. -- `milliseconds` _**optional**_ - - : Integer value representing the millisecond segment of a time.

Values less than 1 indicate that no space should be used. - - If this is a string, the string (or the first 10 characters of the string, if it's longer than that) is inserted before every nested object or array. - - If `space` is anything other than a string or number (can be either a primitive or a wrapper object) — for example, is [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null) or not provided — no white space is used. - -### Return value - -A JSON string representing the given value, or undefined. - -### Exceptions - -- [`TypeError`](../../globals/TypeError/TypeError.mdx) - - : Thrown if one of the following is true: - - `value` contains a circular reference. - - A `BigInt` value is encountered. - -## Description - -`JSON.stringify()` converts a value to JSON notation representing it: - -- `Boolean`, `Number`, `String`, and `BigInt` (obtainable via [`Object()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object/Object)) objects are converted to the corresponding primitive values during stringification, in accordance with the traditional conversion semantics. `Symbol` objects (obtainable via [`Object()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object/Object)) are treated as plain objects. -- Attempting to serialize `BigInt` values will throw. However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result. This constraint ensures that a proper serialization (and, very likely, its accompanying deserialization) behavior is always explicitly provided by the user. -- [`undefined`](../../globals/undefined.mdx), `Function`, and `Symbol` values are not valid JSON values. If any such values are encountered during conversion, they are either omitted (when found in an object) or changed to [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null) (when found in an array). `JSON.stringify()` can return `undefined` when passing in "pure" values like `JSON.stringify(() => {})` or `JSON.stringify(undefined)`. -- The numbers [`Infinity`](../../globals/Infinity.mdx) and [`NaN`](../../globals/NaN.mdx), as well as the value [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null), are all considered `null`. (But unlike the values in the previous point, they would never be omitted.) -- Arrays are serialized as arrays (enclosed by square brackets). Only array indices between 0 and `length - 1` (inclusive) are serialized; other properties are ignored. -- For other objects: - - - All `Symbol`-keyed properties will be completely ignored, even when using the [`replacer`](#the_replacer_parameter) parameter. - - - If the value has a `toJSON()` method, it's responsible to define what data will be serialized. Instead of the object being serialized, the value returned by the `toJSON()` method when called will be serialized. `JSON.stringify()` calls `toJSON` with one parameter, the `key`, which has the same semantic as the `key` parameter of the [`replacer`](#the_replacer_parameter) function: - - - if this object is a property value, the property name - - if it is in an array, the index in the array, as a string - - if `JSON.stringify()` was directly called on this object, an empty string - - `Date` objects implement the [`toJSON()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toJSON) method which returns a string (the same as [`date.toISOString()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)). Thus, they will be stringified as strings. - - - Only [enumerable own properties](https://developer.mozilla.org/docs/Web/JavaScript/Enumerability_and_ownership_of_properties) are visited. This means [Map](../../globals/Map/Map.mdx), [Set](../../globals/Set/Set.mdx), etc. will become `"{}"`. You can use the [`replacer`](#the_replacer_parameter) parameter to serialize them to something more useful. - - Properties are visited using the same algorithm as [`Object.keys()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object/keys), which has a well-defined order and is stable across implementations. For example, `JSON.stringify` on the same object will always produce the same string, and `JSON.parse(JSON.stringify(obj))` would produce an object with the same key ordering as the original (assuming the object is completely JSON-serializable). - -### The replacer parameter - -The `replacer` parameter can be either a function or an array. - -As an array, its elements indicate the names of the properties in the object that should be included in the resulting JSON string. Only string and number values are taken into account; symbol keys are ignored. - -As a function, it takes two parameters: the `key` and the `value` being stringified. The object in which the key was found is provided as the `replacer`'s `this` context. - -The `replacer` function is called for the initial object being stringified as well, in which case the `key` is an empty string (`""`). It is then called for each property on the object or array being stringified. Array indices will be provided in its string form as `key`. The current property value will be replaced with the `replacer`'s return value for stringification. This means: - -- If you return a number, string, boolean, or `null`, that value is directly serialized and used as the property's value. (Returning a BigInt will throw as well.) -- If you return a `Function`, `Symbol`, or [`undefined`](../../globals/undefined.mdx), the property is not included in the output. -- If you return any other object, the object is recursively stringified, calling the `replacer` function on each property. - -> **Note:** When parsing JSON generated with `replacer` functions, you would likely want to use the [`reviver`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#using_the_reviver_parameter) parameter to perform the reverse operation. - -Typically, array elements' index would never shift (even when the element is an invalid value like a function, it will become `null` instead of omitted). Using the `replacer` function allows you to control the order of the array elements by returning a different array. - -### The space parameter - -The `space` parameter may be used to control spacing in the final string. - -- If it is a number, successive levels in the stringification will each be indented by this many space characters. -- If it is a string, successive levels will be indented by this string. - -Each level of indentation will never be longer than 10. Number values of `space` are clamped to 10, and string values are truncated to 10 characters. diff --git a/documentation/versioned_docs/version-1.10.0/globals/Map/@@species.mdx b/documentation/versioned_docs/version-1.10.0/globals/Map/@@species.mdx deleted file mode 100644 index f7617a7f76..0000000000 --- a/documentation/versioned_docs/version-1.10.0/globals/Map/@@species.mdx +++ /dev/null @@ -1,25 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# get Map\[Symbol.species] - -The **`Map[Symbol.species]`** accessor property is an unused accessor property specifying how to copy `Map` objects. - -## Syntax - -```js -Map[Symbol.species] -``` - -### Return value - -The value of the constructor (`this`) on which `get Symbol.species` was called.

Can be any valid JavaScript value (number, - object, function, etc.). - **Defaults to [`undefined`](../../globals/undefined.mdx).** -- `writable` - - : `true` if the value associated with the property may be changed with an - assignment operator. - **Defaults to `false`.** - -An **accessor descriptor** also has the following optional keys: - -- `get` - - : A function which serves as a getter for the property, or [`undefined`](../../globals/undefined.mdx) if - there is no getter. When the property is accessed, this function is called without - arguments and with `this` set to the object through which the property is - accessed (this may not be the object on which the property is defined due to - inheritance). The return value will be used as the value of the property. - **Defaults to [`undefined`](../../globals/undefined.mdx).** -- `set` - - : A function which serves as a setter for the property, or [`undefined`](../../globals/undefined.mdx) if - there is no setter. When the property is assigned, this function is called with one - argument (the value being assigned to the property) and with `this` set to - the object through which the property is assigned. - **Defaults to [`undefined`](../../globals/undefined.mdx).** - -If a descriptor has neither of `value`, `writable`, -`get` and `set` keys, it is treated as a data descriptor. If a -descriptor has both \[`value` or `writable`] and \[`get` or `set`] keys, an exception is thrown. - -Bear in mind that these attributes are not necessarily the descriptor's own properties. -Inherited properties will be considered as well. In order to ensure these defaults are -preserved, you might freeze existing objects in the descriptor object's prototype chain upfront, specify all -options explicitly, or point to [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null) with [`Object.create(null)`](../../globals/Object/create.mdx). - -```js -const obj = {}; -// 1.

It is not possible to change any attribute of a non-configurable accessor property, and it is not possible to switch between data and accessor property types. For data properties with `writable: true`, it is possible to modify the value and change the `writable` attribute from `true` to `false`. A [`TypeError`](../../globals/TypeError/TypeError.mdx) is thrown when attempts are made to change non-configurable property attributes (except `value` and `writable`, if permitted), except when defining a value same as the original value on a data property. - -When the current property is configurable, defining an attribute to `undefined` effectively deletes it. For example, if `o.k` is an accessor property, `Object.defineProperty(o, "k", { set: undefined })` will remove the setter, making `k` only have a getter and become readonly. If an attribute is absent from the new descriptor, the old descriptor attribute's value is kept (it won't be implicitly re-defined to `undefined`). It is possible to toggle between data and accessor property by giving a descriptor of a different "flavor". For example, if the new descriptor is a data descriptor (with `value` or `writable`), the original descriptor's `get` and `set` attributes will both be dropped. diff --git a/documentation/versioned_docs/version-1.10.0/globals/Object/entries.mdx b/documentation/versioned_docs/version-1.10.0/globals/Object/entries.mdx deleted file mode 100644 index 594508e6ab..0000000000 --- a/documentation/versioned_docs/version-1.10.0/globals/Object/entries.mdx +++ /dev/null @@ -1,30 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Object.entries() - -The **`Object.entries()`** method returns an array of a given object's own enumerable string-keyed property key-value pairs. - -## Syntax - -```js -Object.entries(obj) -``` - -### Parameters - -- `obj` - - : An object. - -### Return value - -An array of the given object's own enumerable string-keyed property key-value pairs.

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously). The `then` method will be called with two callbacks, which are two new functions with the exact same behaviors as the `resolveFunc` and `rejectFunc` passed to the `executor` function. If calling the `then` method throws, then the current promise is rejected with the thrown error. - -In the last case, it means code like: - -```js -new Promise((resolve, reject) => { - resolve(thenable); -}); -``` - -Is roughly equivalent to: - -```js -new Promise((resolve, reject) => { - try { - thenable.then( - (value) => resolve(value), - (reason) => reject(reason), - ); - } catch (e) { - reject(e); - } -}); -``` - -Except that in the `resolve(thenable)` case: - -1. `resolve` is called synchronously, so that calling `resolve` or `reject` again has no effect, even when the handlers attached through `anotherPromise.then()` are not called yet. -2. The `then` method is called asynchronously, so that the promise will never be instantly resolved if a thenable is passed. - -Because `resolve` is called again with whatever `thenable.then()` passes to it as `value`, the resolver function is able to flatten nested thenables, where a thenable calls its `onFulfilled` handler with another thenable. The effect is that the fulfillment handler of a real promise will never receive a thenable as its fulfillment value. diff --git a/documentation/versioned_docs/version-1.10.0/globals/Promise/all.mdx b/documentation/versioned_docs/version-1.10.0/globals/Promise/all.mdx deleted file mode 100644 index 1d7912d11f..0000000000 --- a/documentation/versioned_docs/version-1.10.0/globals/Promise/all.mdx +++ /dev/null @@ -1,34 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Promise.all() - -The **`Promise.all()`** method takes an iterable of promises as input and returns a single `Promise`.

Otherwise, the return value of the handler does not affect the state of the original promise. - -## Description - -The `finally()` method can be useful if you want to do some processing or cleanup once the promise is settled, regardless of its outcome. - -The `finally()` method is very similar to calling [`then(onFinally, onFinally)`](../../../globals/Promise/prototype/then.mdx). However, there are a couple of differences: - -- When creating a function inline, you can pass it once, instead of being forced to either declare it twice, or create a variable for it. -- The `onFinally` callback does not receive any argument. This use case is for precisely when you _do not care_ about the rejection reason or the fulfillment value, and so there's no need to provide it. -- A `finally()` call is usually transparent and does not change the eventual state of the original promise. So for example: - - Unlike `Promise.resolve(2).then(() => 77, () => {})`, which returns a promise eventually fulfilled with the value `77`, `Promise.resolve(2).finally(() => 77)` returns a promise eventually fulfilled with the value `2`. - - Similarly, unlike `Promise.reject(3).then(() => {}, () => 88)`, which returns a promise eventually fulfilled with the value `88`, `Promise.reject(3).finally(() => 88)` returns a promise eventually rejected with the reason `3`. - -> **Note:** A `throw` (or returning a rejected promise) in the `finally` callback still rejects the returned promise. For example, both `Promise.reject(3).finally(() => { throw 99; })` and `Promise.reject(3).finally(() => Promise.reject(99))` reject the returned promise with the reason `99`. - -Like [`Promise.prototype.catch()`](../../../globals/Promise/prototype/catch.mdx), `finally()` internally calls the `then` method on the object upon which it was called. If `onFinally` is not a function, `then()` is called with `onFinally` as both arguments — which, for [`Promise.prototype.then()`](../../../globals/Promise/prototype/then.mdx), means that no useful handler is attached. Otherwise, `then()` is called with two internally created functions, which behave like the following: - -> **Warning:** This is only for demonstration purposes and is not a polyfill. - -```js -promise.then( - (value) => Promise.resolve(onFinally()).then(() => value), - (reason) => - Promise.resolve(onFinally()).then(() => { - throw reason; - }), -); -``` - -Because `finally()` calls `then()`, it supports subclassing. Moreover, notice the [`Promise.resolve()`](../../../globals/Promise/resolve.mdx) call above — in reality, `onFinally()`'s return value is resolved using the same algorithm as `Promise.resolve()`, but the actual constructor used to construct the resolved promise will be the subclass. `finally()` gets this constructor through [`promise.constructor[Symbol.species]`](../../../globals/Promise/@@species.mdx). diff --git a/documentation/versioned_docs/version-1.10.0/globals/Promise/prototype/then.mdx b/documentation/versioned_docs/version-1.10.0/globals/Promise/prototype/then.mdx deleted file mode 100644 index 74787b12ac..0000000000 --- a/documentation/versioned_docs/version-1.10.0/globals/Promise/prototype/then.mdx +++ /dev/null @@ -1,53 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Promise.prototype.then() - -The **`then()`** method of a `Promise` object takes up to two arguments: callback functions for the fulfilled and rejected cases of the `Promise`.

It is the primitive method of promises: the [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) protocol expects all promise-like objects to expose a `then()` method, and the [`Promise.prototype.catch`](../../../globals/Promise/prototype/catch.mdx) and [`Promise.prototype.finally`](../../../globals/Promise/prototype/finally.mdx) methods both work by invoking the object's `then()` method. - -For more information about the `onRejected` handler, see the [`Promise.prototype.catch`](../../../globals/Promise/prototype/catch.mdx) reference. - -`then()` returns a new promise object. If you call the `then()` method twice on the same promise object (instead of chaining), then this promise object will have two pairs of settlement handlers. All handlers attached to the same promise object are always called in the order they were added. Moreover, the two promises returned by each call of `then()` start separate chains and do not wait for each other's settlement. - -[Thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) objects that arise along the `then()` chain are always [resolved](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise/Promise#resolver_function) — the `onFulfilled` handler never receives a thenable object, and any thenable returned by either handler are always resolved before being passed to the next handler. This is because when constructing the new promise, the `resolve` and `reject` functions passed by the `executor` are saved, and when the current promise settles, the respective function will be called with the fulfillment value or rejection reason. The resolving logic comes from the resolver function passed by the [`Promise()`](../../../globals/Promise/Promise.mdx) constructor. - -`then()` supports subclassing, which means it can be called on instances of subclasses of `Promise`, and the result will be a promise of the subclass type.

A library can help if many different formats are to be accommodated. - > - > Date-only strings (e.g. `"1970-01-01"`) are treated as UTC, while date-time strings (e.g. `"1970-01-01T12:00"`) are treated as local. You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. - -If any parameter overflows its defined bounds, it "carries over". For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M. June 20th, 2020. - -Similarly, if any parameter underflows, it "borrows" from the higher positions. For example, `new Date(2020, 5, 0)` will return May 31st, 2020. - -- `year` - - : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year. See the [example](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date#interpretation_of_two-digit_years). -- `monthIndex` - - : Integer value representing the month, beginning with `0` for January to `11` for December. -- `day` _**optional**_ - - : Integer value representing the day of the month. The default is `1`. -- `hours` _**optional**_ - - : Integer value between `0` and `23` representing the hour of the day. Defaults to `0`. -- `minutes` _**optional**_ - - : Integer value representing the minute segment of a time. The default is `0` minutes past the hour. -- `seconds` _**optional**_ - - : Integer value representing the second segment of a time. The default is `0` seconds past the minute. -- `milliseconds` _**optional**_ - - : Integer value representing the millisecond segment of a time. The default is `0` milliseconds past the second. - -### Return value - -Calling `new Date()` (the `Date()` constructor) returns a [`Date`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date) object. If called with an invalid date string, or if the date to be constructed will have a UNIX timestamp less than `-8,640,000,000,000,000` or greater than `8,640,000,000,000,000` milliseconds, it returns a `Date` object whose [`toString()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toString) method returns the literal string `Invalid Date`. - -Calling the `Date()` function (without the `new` keyword) returns a string representation of the current date and time, exactly as `new Date().toString()` does. Any arguments given in a `Date()` function call (without the `new` keyword) are ignored; regardless of whether it's called with an invalid date string — or even called with any arbitrary object or other primitive as an argument — it always returns a string representation of the current date and time. diff --git a/documentation/versioned_docs/version-1.11.0/globals/Date/UTC.mdx b/documentation/versioned_docs/version-1.11.0/globals/Date/UTC.mdx deleted file mode 100644 index 472ad546cf..0000000000 --- a/documentation/versioned_docs/version-1.11.0/globals/Date/UTC.mdx +++ /dev/null @@ -1,84 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Date.UTC() - -The **`Date.UTC()`** method accepts parameters similar to the -`Date` constructor, but treats them as UTC.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result. This constraint ensures that a proper serialization (and, very likely, its accompanying deserialization) behavior is always explicitly provided by the user. -- [`undefined`](../../globals/undefined.mdx), `Function`, and `Symbol` values are not valid JSON values. If any such values are encountered during conversion, they are either omitted (when found in an object) or changed to [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null) (when found in an array). `JSON.stringify()` can return `undefined` when passing in "pure" values like `JSON.stringify(() => {})` or `JSON.stringify(undefined)`. -- The numbers [`Infinity`](../../globals/Infinity.mdx) and [`NaN`](../../globals/NaN.mdx), as well as the value [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null), are all considered `null`.

Instead of the object being serialized, the value returned by the `toJSON()` method when called will be serialized. `JSON.stringify()` calls `toJSON` with one parameter, the `key`, which has the same semantic as the `key` parameter of the [`replacer`](#the_replacer_parameter) function: - - - if this object is a property value, the property name - - if it is in an array, the index in the array, as a string - - if `JSON.stringify()` was directly called on this object, an empty string - - `Date` objects implement the [`toJSON()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toJSON) method which returns a string (the same as [`date.toISOString()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)).

For example, `JSON.stringify` on the same object will always produce the same string, and `JSON.parse(JSON.stringify(obj))` would produce an object with the same key ordering as the original (assuming the object is completely JSON-serializable). - -### The replacer parameter - -The `replacer` parameter can be either a function or an array. - -As an array, its elements indicate the names of the properties in the object that should be included in the resulting JSON string.

It is then called for each property on the object or array being stringified. Array indices will be provided in its string form as `key`. The current property value will be replaced with the `replacer`'s return value for stringification. This means: - -- If you return a number, string, boolean, or `null`, that value is directly serialized and used as the property's value. (Returning a BigInt will throw as well.) -- If you return a `Function`, `Symbol`, or [`undefined`](../../globals/undefined.mdx), the property is not included in the output. -- If you return any other object, the object is recursively stringified, calling the `replacer` function on each property. - -> **Note:** When parsing JSON generated with `replacer` functions, you would likely want to use the [`reviver`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#using_the_reviver_parameter) parameter to perform the reverse operation. - -Typically, array elements' index would never shift (even when the element is an invalid value like a function, it will become `null` instead of omitted).

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously).

-If a chunk of data is supplied, the `value` property will contain a new view. -This will be a view over the same buffer/backing memory (and of the same type) as the original `view` passed to the `read()` method, now populated with the new chunk of data. -Note that once the promise fulfills, the original `view` passed to the method will be detached and no longer usable. -The promise will fulfill with a `value: undefined` if the stream has been cancelled. -In this case the backing memory region of `view` is discarded and not returned to the caller (all previously read data in the view's buffer is lost). -

For example, `parseInt("42")` and `parseFloat("42")` would return the same value: a `Number` 42. - -## Description - -The `parseInt` function converts its first argument to a string, parses that string, then returns an integer or `NaN`. - -If not `NaN`, the return value will be the integer that is the first argument taken as a number in the specified `radix`.

If it's unprovided, or if the value becomes 0, `NaN` or `Infinity` (`undefined` is coerced to `NaN`), JavaScript assumes the following: - -1. If the input `string`, with leading whitespace and possible `+`/`-` signs removed, begins with `0x` or `0X` (a zero, followed by lowercase or uppercase X), `radix` is assumed to be `16` and the rest of the string is parsed as a hexadecimal number. -2. If the input `string` begins with any other value, the radix is `10` (decimal). - -> **Note:** Other prefixes like `0b`, which are valid in [number literals](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Lexical_grammar#binary), are treated as normal digits by `parseInt()`. `parseInt()` does _not_ treat strings beginning with a `0` character as octal values either. The only prefix that `parseInt()` recognizes is `0x` or `0X` for hexadecimal values — everything else is parsed as a decimal value if `radix` is missing. - -If the radix is `16`, `parseInt()` allows the string to be optionally prefixed by `0x` or `0X` after the optional sign character (`+`/`-`). - -If the radix value (coerced if necessary) is not in range \[2, 36] (inclusive) `parseInt` returns `NaN`. - -For radices above `10`, letters of the English alphabet indicate numerals greater than `9`. For example, for hexadecimal numbers (base `16`), `A` through `F` are used. The letters are case-insensitive. - -`parseInt` understands exactly two signs: `+` for positive, and `-` for negative. It is done as an initial step in the parsing after whitespace is removed. If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point. For example, although `1e3` technically encodes an integer (and will be correctly parsed to the integer `1000` by [`parseFloat()`](./parseFloat.mdx), `parseInt("1e3", 10)` returns `1`, because `e` is not a valid numeral in base 10. Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

Keep in mind that most [UNIX Timestamp](https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_16) functions are only accurate to the nearest second. - -#### Date string - -- `dateString` - - - : A string value representing a date, in a format recognized by the [`Date.parse()`](./parse.mdx) method. (The ECMA262 spec specifies a [simplified version of ISO 8601](https://tc39.es/ecma262/#sec-date-time-string-format), but other formats can be implementation-defined, which commonly include [IETF-compliant RFC 2822 timestamps](https://datatracker.ietf.org/doc/html/rfc2822#page-14).) - - > **Note:** When parsing date strings with the `Date` constructor (and `Date.parse`, they are equivalent), always make sure that the input conforms to the ISO 8601 format (`YYYY-MM-DDTHH:mm:ss.sssZ`) — the parsing behavior with other formats is implementation-defined and may not work across all browsers. Support for [RFC 2822](https://datatracker.ietf.org/doc/html/rfc2822) format strings is by convention only. A library can help if many different formats are to be accommodated. - > - > Date-only strings (e.g. `"1970-01-01"`) are treated as UTC, while date-time strings (e.g. `"1970-01-01T12:00"`) are treated as local. You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. - -If any parameter overflows its defined bounds, it "carries over". For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M. June 20th, 2020. - -Similarly, if any parameter underflows, it "borrows" from the higher positions. For example, `new Date(2020, 5, 0)` will return May 31st, 2020. - -- `year` - - : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year. See the [example](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date#interpretation_of_two-digit_years). -- `monthIndex` - - : Integer value representing the month, beginning with `0` for January to `11` for December. -- `day` _**optional**_ - - : Integer value representing the day of the month. The default is `1`. -- `hours` _**optional**_ - - : Integer value between `0` and `23` representing the hour of the day. Defaults to `0`. -- `minutes` _**optional**_ - - : Integer value representing the minute segment of a time. The default is `0` minutes past the hour. -- `seconds` _**optional**_ - - : Integer value representing the second segment of a time. The default is `0` seconds past the minute. -- `milliseconds` _**optional**_ - - : Integer value representing the millisecond segment of a time.

In such cases, the name can be inferred, as the following few subsections demonstrate. - -One practical case where the name cannot be inferred is a function returned from another function: - -```js -function getFoo() { - return () => {}; -} -getFoo().name; // "" -``` - -### Variable declaration and method - -Variables and methods can infer the name of an anonymous function from its syntactic position. - -```js -const f = function () {}; -const object = { - someMethod: function () {} -}; - -console.log(f.name); // "f" -console.log(object.someMethod.name); // "someMethod" -``` - -The same applies to assignment: - -```js -let f; -f = () => {}; -f.name; // "f" -``` - -### Initializer and default value - -Functions in initializers (default values) of [destructuring](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment#default_value), [default parameters](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/Default_parameters), [class fields](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Classes/Public_class_fields), etc., will inherit the name of the bound identifier as their `name`. - -```js -const [f = () => {}] = []; -f.name; // "f" - -const { someMethod: m = () => {} } = {}; -m.name; // "m" - -function foo(f = () => {}) { - console.log(f.name); -} -foo(); // "f" - -class Foo { - static someMethod = () => {}; -} -Foo.someMethod.name; // someMethod -``` - -### Shorthand method - -```js -const o = { - foo() {}, -}; -o.foo.name; // "foo"; -``` - -### Bound function - -[`Function.prototype.bind()`](../../../globals/Function/prototype/bind.mdx) produces a function whose name is "bound " plus the function name. - -```js -function foo() {}; -foo.bind({}).name; // "bound foo" -``` - -### Getter and setter - -When using [`get`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/get) and [`set`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/set) accessor properties, "get" or "set" will appear in the function name. - -```js -const o = { - get foo() {}, - set foo(x) {}, -}; - -const descriptor = Object.getOwnPropertyDescriptor(o, "foo"); -descriptor.get.name; // "get foo" -descriptor.set.name; // "set foo"; -``` - -### Class - -A class's name follows the same algorithm as function declarations and expressions. - -```js -class Foo {} -Foo.name; // "Foo" -``` - -> **Warning:** JavaScript will set the function's `name` property only if a function does not have an own property called `name`. However, classes' [static members](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Classes/static) will be set as own properties of the class constructor function, and thus prevent the built-in `name` from being applied. See [an example](#telling_the_constructor_name_of_an_object) below. - -### Symbol as function name - -If a `Symbol` is used a function name and the symbol has a description, the method's name is the description in square brackets. - -```js -const sym1 = Symbol("foo"); -const sym2 = Symbol(); - -const o = { - [sym1]() {}, - [sym2]() {}, -}; - -o[sym1].name; // "[foo]" -o[sym2].name; // "[]" -``` - -### Private property - -Private fields and private methods have the hash (`#`) as part of their names. - -```js -class Foo { - #field = () => {}; - #method() {} - getNames() { - console.log(this.#field.name); - console.log(this.#method.name); - } -} - -new Foo().getNames(); -// "#field" -// "#method" -``` diff --git a/documentation/versioned_docs/version-1.12.0/globals/Function/prototype/toString.mdx b/documentation/versioned_docs/version-1.12.0/globals/Function/prototype/toString.mdx deleted file mode 100644 index c2b4572389..0000000000 --- a/documentation/versioned_docs/version-1.12.0/globals/Function/prototype/toString.mdx +++ /dev/null @@ -1,60 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Function.prototype.toString() - -The **`toString()`** method returns a string representing the source code of the specified `Function`. - -## Syntax - -```js -toString() -``` - -### Return value - -A string representing the source code of the function. - -## Description - -The `Function` object overrides the `toString()` method -inherited from `Object`; it does not inherit -[`Object.prototype.toString()`](../../../globals/Object/prototype/toString.mdx).

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result. This constraint ensures that a proper serialization (and, very likely, its accompanying deserialization) behavior is always explicitly provided by the user. -- [`undefined`](../../globals/undefined.mdx), `Function`, and `Symbol` values are not valid JSON values. If any such values are encountered during conversion, they are either omitted (when found in an object) or changed to [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null) (when found in an array). `JSON.stringify()` can return `undefined` when passing in "pure" values like `JSON.stringify(() => {})` or `JSON.stringify(undefined)`. -- The numbers [`Infinity`](../../globals/Infinity.mdx) and [`NaN`](../../globals/NaN.mdx), as well as the value [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null), are all considered `null`. (But unlike the values in the previous point, they would never be omitted.) -- Arrays are serialized as arrays (enclosed by square brackets). Only array indices between 0 and `length - 1` (inclusive) are serialized; other properties are ignored. -- For other objects: - - - All `Symbol`-keyed properties will be completely ignored, even when using the [`replacer`](#the_replacer_parameter) parameter. - - - If the value has a `toJSON()` method, it's responsible to define what data will be serialized. Instead of the object being serialized, the value returned by the `toJSON()` method when called will be serialized. `JSON.stringify()` calls `toJSON` with one parameter, the `key`, which has the same semantic as the `key` parameter of the [`replacer`](#the_replacer_parameter) function: - - - if this object is a property value, the property name - - if it is in an array, the index in the array, as a string - - if `JSON.stringify()` was directly called on this object, an empty string - - `Date` objects implement the [`toJSON()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toJSON) method which returns a string (the same as [`date.toISOString()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)). Thus, they will be stringified as strings. - - - Only [enumerable own properties](https://developer.mozilla.org/docs/Web/JavaScript/Enumerability_and_ownership_of_properties) are visited. This means [Map](../../globals/Map/Map.mdx), [Set](../../globals/Set/Set.mdx), etc. will become `"{}"`. You can use the [`replacer`](#the_replacer_parameter) parameter to serialize them to something more useful. - - Properties are visited using the same algorithm as [`Object.keys()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object/keys), which has a well-defined order and is stable across implementations. For example, `JSON.stringify` on the same object will always produce the same string, and `JSON.parse(JSON.stringify(obj))` would produce an object with the same key ordering as the original (assuming the object is completely JSON-serializable). - -### The replacer parameter - -The `replacer` parameter can be either a function or an array. - -As an array, its elements indicate the names of the properties in the object that should be included in the resulting JSON string. Only string and number values are taken into account; symbol keys are ignored. - -As a function, it takes two parameters: the `key` and the `value` being stringified. The object in which the key was found is provided as the `replacer`'s `this` context. - -The `replacer` function is called for the initial object being stringified as well, in which case the `key` is an empty string (`""`). It is then called for each property on the object or array being stringified. Array indices will be provided in its string form as `key`. The current property value will be replaced with the `replacer`'s return value for stringification. This means: - -- If you return a number, string, boolean, or `null`, that value is directly serialized and used as the property's value. (Returning a BigInt will throw as well.) -- If you return a `Function`, `Symbol`, or [`undefined`](../../globals/undefined.mdx), the property is not included in the output. -- If you return any other object, the object is recursively stringified, calling the `replacer` function on each property. - -> **Note:** When parsing JSON generated with `replacer` functions, you would likely want to use the [`reviver`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#using_the_reviver_parameter) parameter to perform the reverse operation. - -Typically, array elements' index would never shift (even when the element is an invalid value like a function, it will become `null` instead of omitted).

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously). The `then` method will be called with two callbacks, which are two new functions with the exact same behaviors as the `resolveFunc` and `rejectFunc` passed to the `executor` function. If calling the `then` method throws, then the current promise is rejected with the thrown error. - -In the last case, it means code like: - -```js -new Promise((resolve, reject) => { - resolve(thenable); -}); -``` - -Is roughly equivalent to: - -```js -new Promise((resolve, reject) => { - try { - thenable.then( - (value) => resolve(value), - (reason) => reject(reason), - ); - } catch (e) { - reject(e); - } -}); -``` - -Except that in the `resolve(thenable)` case: - -1. `resolve` is called synchronously, so that calling `resolve` or `reject` again has no effect, even when the handlers attached through `anotherPromise.then()` are not called yet. -2. The `then` method is called asynchronously, so that the promise will never be instantly resolved if a thenable is passed. - -Because `resolve` is called again with whatever `thenable.then()` passes to it as `value`, the resolver function is able to flatten nested thenables, where a thenable calls its `onFulfilled` handler with another thenable. The effect is that the fulfillment handler of a real promise will never receive a thenable as its fulfillment value. diff --git a/documentation/versioned_docs/version-1.12.0/globals/Promise/all.mdx b/documentation/versioned_docs/version-1.12.0/globals/Promise/all.mdx deleted file mode 100644 index 1d7912d11f..0000000000 --- a/documentation/versioned_docs/version-1.12.0/globals/Promise/all.mdx +++ /dev/null @@ -1,34 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Promise.all() - -The **`Promise.all()`** method takes an iterable of promises as input and returns a single `Promise`.

Otherwise, the return value of the handler does not affect the state of the original promise. - -## Description - -The `finally()` method can be useful if you want to do some processing or cleanup once the promise is settled, regardless of its outcome. - -The `finally()` method is very similar to calling [`then(onFinally, onFinally)`](../../../globals/Promise/prototype/then.mdx). However, there are a couple of differences: - -- When creating a function inline, you can pass it once, instead of being forced to either declare it twice, or create a variable for it. -- The `onFinally` callback does not receive any argument. This use case is for precisely when you _do not care_ about the rejection reason or the fulfillment value, and so there's no need to provide it. -- A `finally()` call is usually transparent and does not change the eventual state of the original promise. So for example: - - Unlike `Promise.resolve(2).then(() => 77, () => {})`, which returns a promise eventually fulfilled with the value `77`, `Promise.resolve(2).finally(() => 77)` returns a promise eventually fulfilled with the value `2`. - - Similarly, unlike `Promise.reject(3).then(() => {}, () => 88)`, which returns a promise eventually fulfilled with the value `88`, `Promise.reject(3).finally(() => 88)` returns a promise eventually rejected with the reason `3`. - -> **Note:** A `throw` (or returning a rejected promise) in the `finally` callback still rejects the returned promise. For example, both `Promise.reject(3).finally(() => { throw 99; })` and `Promise.reject(3).finally(() => Promise.reject(99))` reject the returned promise with the reason `99`. - -Like [`Promise.prototype.catch()`](../../../globals/Promise/prototype/catch.mdx), `finally()` internally calls the `then` method on the object upon which it was called. If `onFinally` is not a function, `then()` is called with `onFinally` as both arguments — which, for [`Promise.prototype.then()`](../../../globals/Promise/prototype/then.mdx), means that no useful handler is attached. Otherwise, `then()` is called with two internally created functions, which behave like the following: - -> **Warning:** This is only for demonstration purposes and is not a polyfill. - -```js -promise.then( - (value) => Promise.resolve(onFinally()).then(() => value), - (reason) => - Promise.resolve(onFinally()).then(() => { - throw reason; - }), -); -``` - -Because `finally()` calls `then()`, it supports subclassing. Moreover, notice the [`Promise.resolve()`](../../../globals/Promise/resolve.mdx) call above — in reality, `onFinally()`'s return value is resolved using the same algorithm as `Promise.resolve()`, but the actual constructor used to construct the resolved promise will be the subclass. `finally()` gets this constructor through [`promise.constructor[Symbol.species]`](../../../globals/Promise/@@species.mdx). diff --git a/documentation/versioned_docs/version-1.12.0/globals/Promise/prototype/then.mdx b/documentation/versioned_docs/version-1.12.0/globals/Promise/prototype/then.mdx deleted file mode 100644 index 74787b12ac..0000000000 --- a/documentation/versioned_docs/version-1.12.0/globals/Promise/prototype/then.mdx +++ /dev/null @@ -1,53 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Promise.prototype.then() - -The **`then()`** method of a `Promise` object takes up to two arguments: callback functions for the fulfilled and rejected cases of the `Promise`.

It is the primitive method of promises: the [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) protocol expects all promise-like objects to expose a `then()` method, and the [`Promise.prototype.catch`](../../../globals/Promise/prototype/catch.mdx) and [`Promise.prototype.finally`](../../../globals/Promise/prototype/finally.mdx) methods both work by invoking the object's `then()` method. - -For more information about the `onRejected` handler, see the [`Promise.prototype.catch`](../../../globals/Promise/prototype/catch.mdx) reference. - -`then()` returns a new promise object. If you call the `then()` method twice on the same promise object (instead of chaining), then this promise object will have two pairs of settlement handlers. All handlers attached to the same promise object are always called in the order they were added. Moreover, the two promises returned by each call of `then()` start separate chains and do not wait for each other's settlement. - -[Thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) objects that arise along the `then()` chain are always [resolved](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise/Promise#resolver_function) — the `onFulfilled` handler never receives a thenable object, and any thenable returned by either handler are always resolved before being passed to the next handler. This is because when constructing the new promise, the `resolve` and `reject` functions passed by the `executor` are saved, and when the current promise settles, the respective function will be called with the fulfillment value or rejection reason. The resolving logic comes from the resolver function passed by the [`Promise()`](../../../globals/Promise/Promise.mdx) constructor. - -`then()` supports subclassing, which means it can be called on instances of subclasses of `Promise`, and the result will be a promise of the subclass type.

Once a proxy is revoked, it remains revoked, and calling `revoke()` again has no effect — in fact, the call to `revoke()` detaches the `proxy` object from the `revoke` function, so the `revoke` function will not be able to access the proxy again at all. If the proxy is not referenced elsewhere, it will then be eligible for garbage collection.

-If a chunk of data is supplied, the `value` property will contain a new view. -This will be a view over the same buffer/backing memory (and of the same type) as the original `view` passed to the `read()` method, now populated with the new chunk of data. -Note that once the promise fulfills, the original `view` passed to the method will be detached and no longer usable. -The promise will fulfill with a `value: undefined` if the stream has been cancelled. -In this case the backing memory region of `view` is discarded and not returned to the caller (all previously read data in the view's buffer is lost). -

For example, `parseInt("42")` and `parseFloat("42")` would return the same value: a `Number` 42. - -## Description - -The `parseInt` function converts its first argument to a string, parses that string, then returns an integer or `NaN`. - -If not `NaN`, the return value will be the integer that is the first argument taken as a number in the specified `radix`.

If it's unprovided, or if the value becomes 0, `NaN` or `Infinity` (`undefined` is coerced to `NaN`), JavaScript assumes the following: - -1. If the input `string`, with leading whitespace and possible `+`/`-` signs removed, begins with `0x` or `0X` (a zero, followed by lowercase or uppercase X), `radix` is assumed to be `16` and the rest of the string is parsed as a hexadecimal number. -2. If the input `string` begins with any other value, the radix is `10` (decimal). - -> **Note:** Other prefixes like `0b`, which are valid in [number literals](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Lexical_grammar#binary), are treated as normal digits by `parseInt()`. `parseInt()` does _not_ treat strings beginning with a `0` character as octal values either. The only prefix that `parseInt()` recognizes is `0x` or `0X` for hexadecimal values — everything else is parsed as a decimal value if `radix` is missing. - -If the radix is `16`, `parseInt()` allows the string to be optionally prefixed by `0x` or `0X` after the optional sign character (`+`/`-`). - -If the radix value (coerced if necessary) is not in range \[2, 36] (inclusive) `parseInt` returns `NaN`. - -For radices above `10`, letters of the English alphabet indicate numerals greater than `9`. For example, for hexadecimal numbers (base `16`), `A` through `F` are used. The letters are case-insensitive. - -`parseInt` understands exactly two signs: `+` for positive, and `-` for negative. It is done as an initial step in the parsing after whitespace is removed. If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point. For example, although `1e3` technically encodes an integer (and will be correctly parsed to the integer `1000` by [`parseFloat()`](./parseFloat.mdx), `parseInt("1e3", 10)` returns `1`, because `e` is not a valid numeral in base 10. Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

(The ECMA262 spec specifies a [simplified version of ISO 8601](https://tc39.es/ecma262/#sec-date-time-string-format), but other formats can be implementation-defined, which commonly include [IETF-compliant RFC 2822 timestamps](https://datatracker.ietf.org/doc/html/rfc2822#page-14).) - - > **Note:** When parsing date strings with the `Date` constructor (and `Date.parse`, they are equivalent), always make sure that the input conforms to the ISO 8601 format (`YYYY-MM-DDTHH:mm:ss.sssZ`) — the parsing behavior with other formats is implementation-defined and may not work across all browsers.

You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. - -If any parameter overflows its defined bounds, it "carries over". For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M. June 20th, 2020. - -Similarly, if any parameter underflows, it "borrows" from the higher positions. For example, `new Date(2020, 5, 0)` will return May 31st, 2020. - -- `year` - - : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result. This constraint ensures that a proper serialization (and, very likely, its accompanying deserialization) behavior is always explicitly provided by the user. -- [`undefined`](../../globals/undefined.mdx), `Function`, and `Symbol` values are not valid JSON values. If any such values are encountered during conversion, they are either omitted (when found in an object) or changed to [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null) (when found in an array). `JSON.stringify()` can return `undefined` when passing in "pure" values like `JSON.stringify(() => {})` or `JSON.stringify(undefined)`. -- The numbers [`Infinity`](../../globals/Infinity.mdx) and [`NaN`](../../globals/NaN.mdx), as well as the value [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null), are all considered `null`.

Instead of the object being serialized, the value returned by the `toJSON()` method when called will be serialized. `JSON.stringify()` calls `toJSON` with one parameter, the `key`, which has the same semantic as the `key` parameter of the [`replacer`](#the_replacer_parameter) function: - - - if this object is a property value, the property name - - if it is in an array, the index in the array, as a string - - if `JSON.stringify()` was directly called on this object, an empty string - - `Date` objects implement the [`toJSON()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toJSON) method which returns a string (the same as [`date.toISOString()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)). Thus, they will be stringified as strings. - - - Only [enumerable own properties](https://developer.mozilla.org/docs/Web/JavaScript/Enumerability_and_ownership_of_properties) are visited. This means [Map](../../globals/Map/Map.mdx), [Set](../../globals/Set/Set.mdx), etc. will become `"{}"`. You can use the [`replacer`](#the_replacer_parameter) parameter to serialize them to something more useful. - - Properties are visited using the same algorithm as [`Object.keys()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object/keys), which has a well-defined order and is stable across implementations. For example, `JSON.stringify` on the same object will always produce the same string, and `JSON.parse(JSON.stringify(obj))` would produce an object with the same key ordering as the original (assuming the object is completely JSON-serializable). - -### The replacer parameter - -The `replacer` parameter can be either a function or an array. - -As an array, its elements indicate the names of the properties in the object that should be included in the resulting JSON string.

The object in which the key was found is provided as the `replacer`'s `this` context. - -The `replacer` function is called for the initial object being stringified as well, in which case the `key` is an empty string (`""`). It is then called for each property on the object or array being stringified. Array indices will be provided in its string form as `key`. The current property value will be replaced with the `replacer`'s return value for stringification. This means: - -- If you return a number, string, boolean, or `null`, that value is directly serialized and used as the property's value. (Returning a BigInt will throw as well.) -- If you return a `Function`, `Symbol`, or [`undefined`](../../globals/undefined.mdx), the property is not included in the output. -- If you return any other object, the object is recursively stringified, calling the `replacer` function on each property. - -> **Note:** When parsing JSON generated with `replacer` functions, you would likely want to use the [`reviver`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#using_the_reviver_parameter) parameter to perform the reverse operation. - -Typically, array elements' index would never shift (even when the element is an invalid value like a function, it will become `null` instead of omitted).

For example, `5.0000000000000001` only differs from `5` by `1e-16`, which is too small to be represented. (For reference, [`Number.EPSILON`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number/EPSILON) stores the distance between 1 and the next representable floating-point number greater than 1, and that is about `2.22e-16`.) Therefore, `5.0000000000000001` will be represented with the same encoding as `5`, thus making `Number.isInteger(5.0000000000000001)` return `true`. - -In a similar sense, numbers around the magnitude of [`Number.MAX_SAFE_INTEGER`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number/MAX_SAFE_INTEGER) will suffer from loss of precision and make `Number.isInteger` return `true` even when it's not an integer. (The actual threshold varies based on how many bits are needed to represent the decimal — for example, `Number.isInteger(4500000000000000.1)` is `true`, but `Number.isInteger(4500000000000000.5)` is `false`.) diff --git a/documentation/versioned_docs/version-1.2.0/globals/Number/isNaN.mdx b/documentation/versioned_docs/version-1.2.0/globals/Number/isNaN.mdx deleted file mode 100644 index 2244aabc9d..0000000000 --- a/documentation/versioned_docs/version-1.2.0/globals/Number/isNaN.mdx +++ /dev/null @@ -1,32 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Number.isNaN() - -The **`Number.isNaN()`** method determines whether the passed value is the number value [`NaN`](../../globals/NaN.mdx), and returns `false` if the input is not of the Number type.

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously). The `then` method will be called with two callbacks, which are two new functions with the exact same behaviors as the `resolveFunc` and `rejectFunc` passed to the `executor` function. If calling the `then` method throws, then the current promise is rejected with the thrown error. - -In the last case, it means code like: - -```js -new Promise((resolve, reject) => { - resolve(thenable); -}); -``` - -Is roughly equivalent to: - -```js -new Promise((resolve, reject) => { - try { - thenable.then( - (value) => resolve(value), - (reason) => reject(reason), - ); - } catch (e) { - reject(e); - } -}); -``` - -Except that in the `resolve(thenable)` case: - -1. `resolve` is called synchronously, so that calling `resolve` or `reject` again has no effect, even when the handlers attached through `anotherPromise.then()` are not called yet. -2. The `then` method is called asynchronously, so that the promise will never be instantly resolved if a thenable is passed. - -Because `resolve` is called again with whatever `thenable.then()` passes to it as `value`, the resolver function is able to flatten nested thenables, where a thenable calls its `onFulfilled` handler with another thenable. The effect is that the fulfillment handler of a real promise will never receive a thenable as its fulfillment value. diff --git a/documentation/versioned_docs/version-1.2.0/globals/Promise/all.mdx b/documentation/versioned_docs/version-1.2.0/globals/Promise/all.mdx deleted file mode 100644 index 1d7912d11f..0000000000 --- a/documentation/versioned_docs/version-1.2.0/globals/Promise/all.mdx +++ /dev/null @@ -1,34 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Promise.all() - -The **`Promise.all()`** method takes an iterable of promises as input and returns a single `Promise`.

Otherwise, the return value of the handler does not affect the state of the original promise. - -## Description - -The `finally()` method can be useful if you want to do some processing or cleanup once the promise is settled, regardless of its outcome. - -The `finally()` method is very similar to calling [`then(onFinally, onFinally)`](../../../globals/Promise/prototype/then.mdx). However, there are a couple of differences: - -- When creating a function inline, you can pass it once, instead of being forced to either declare it twice, or create a variable for it. -- The `onFinally` callback does not receive any argument. This use case is for precisely when you _do not care_ about the rejection reason or the fulfillment value, and so there's no need to provide it. -- A `finally()` call is usually transparent and does not change the eventual state of the original promise. So for example: - - Unlike `Promise.resolve(2).then(() => 77, () => {})`, which returns a promise eventually fulfilled with the value `77`, `Promise.resolve(2).finally(() => 77)` returns a promise eventually fulfilled with the value `2`. - - Similarly, unlike `Promise.reject(3).then(() => {}, () => 88)`, which returns a promise eventually fulfilled with the value `88`, `Promise.reject(3).finally(() => 88)` returns a promise eventually rejected with the reason `3`. - -> **Note:** A `throw` (or returning a rejected promise) in the `finally` callback still rejects the returned promise. For example, both `Promise.reject(3).finally(() => { throw 99; })` and `Promise.reject(3).finally(() => Promise.reject(99))` reject the returned promise with the reason `99`. - -Like [`Promise.prototype.catch()`](../../../globals/Promise/prototype/catch.mdx), `finally()` internally calls the `then` method on the object upon which it was called. If `onFinally` is not a function, `then()` is called with `onFinally` as both arguments — which, for [`Promise.prototype.then()`](../../../globals/Promise/prototype/then.mdx), means that no useful handler is attached. Otherwise, `then()` is called with two internally created functions, which behave like the following: - -> **Warning:** This is only for demonstration purposes and is not a polyfill. - -```js -promise.then( - (value) => Promise.resolve(onFinally()).then(() => value), - (reason) => - Promise.resolve(onFinally()).then(() => { - throw reason; - }), -); -``` - -Because `finally()` calls `then()`, it supports subclassing. Moreover, notice the [`Promise.resolve()`](../../../globals/Promise/resolve.mdx) call above — in reality, `onFinally()`'s return value is resolved using the same algorithm as `Promise.resolve()`, but the actual constructor used to construct the resolved promise will be the subclass. `finally()` gets this constructor through [`promise.constructor[Symbol.species]`](../../../globals/Promise/@@species.mdx). diff --git a/documentation/versioned_docs/version-1.2.0/globals/Promise/prototype/then.mdx b/documentation/versioned_docs/version-1.2.0/globals/Promise/prototype/then.mdx deleted file mode 100644 index 74787b12ac..0000000000 --- a/documentation/versioned_docs/version-1.2.0/globals/Promise/prototype/then.mdx +++ /dev/null @@ -1,53 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Promise.prototype.then() - -The **`then()`** method of a `Promise` object takes up to two arguments: callback functions for the fulfilled and rejected cases of the `Promise`.

It is the primitive method of promises: the [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) protocol expects all promise-like objects to expose a `then()` method, and the [`Promise.prototype.catch`](../../../globals/Promise/prototype/catch.mdx) and [`Promise.prototype.finally`](../../../globals/Promise/prototype/finally.mdx) methods both work by invoking the object's `then()` method. - -For more information about the `onRejected` handler, see the [`Promise.prototype.catch`](../../../globals/Promise/prototype/catch.mdx) reference. - -`then()` returns a new promise object. If you call the `then()` method twice on the same promise object (instead of chaining), then this promise object will have two pairs of settlement handlers. All handlers attached to the same promise object are always called in the order they were added. Moreover, the two promises returned by each call of `then()` start separate chains and do not wait for each other's settlement. - -[Thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) objects that arise along the `then()` chain are always [resolved](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise/Promise#resolver_function) — the `onFulfilled` handler never receives a thenable object, and any thenable returned by either handler are always resolved before being passed to the next handler. This is because when constructing the new promise, the `resolve` and `reject` functions passed by the `executor` are saved, and when the current promise settles, the respective function will be called with the fulfillment value or rejection reason. The resolving logic comes from the resolver function passed by the [`Promise()`](../../../globals/Promise/Promise.mdx) constructor. - -`then()` supports subclassing, which means it can be called on instances of subclasses of `Promise`, and the result will be a promise of the subclass type.

The `"default"` hint is used by the [primitive coercion](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion) algorithm. The `hint` only acts as a weak signal of preference, and the implementation is free to ignore it (as [`Symbol.prototype[Symbol.toPrimitive]()`](../../globals/Symbol/prototype/@@toPrimitive.mdx) does). The language does not enforce alignment between the `hint` and the result type, although `[Symbol.toPrimitive]()` must return a primitive, or a [`TypeError`](../../globals/TypeError/TypeError.mdx) is thrown. - -Objects without the `Symbol.toPrimitive` property are converted to primitives by calling the `valueOf()` and `toString()` methods in different orders, which is explained in more detail in the [type coercion](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#type_coercion) section. `Symbol.toPrimitive` allows full control over the primitive conversion process.

If `isNaN(x)` returns `true`, `x` will get coerced to `NaN` and make most arithmetic expressions return `NaN` (because `NaN` propagates).

If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point.

Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters.

For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result.

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously).

If `isNaN(x)` returns `true`, `x` will get coerced to `NaN` and make most arithmetic expressions return `NaN` (because `NaN` propagates).

If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point. For example, although `1e3` technically encodes an integer (and will be correctly parsed to the integer `1000` by [`parseFloat()`](./parseFloat.mdx), `parseInt("1e3", 10)` returns `1`, because `e` is not a valid numeral in base 10. Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

When the time zone offset is absent, -date-only forms are interpreted as a UTC time and date-time forms are interpreted as -local time. - -While time zone specifiers are used during date string parsing to interpret the -argument, the value returned is always the number of milliseconds between January 1, -1970 00:00:00 UTC and the point in time represented by the argument or `NaN`. - -Because `parse()` is a static method of `Date`, it is called as -`Date.parse()` rather than as a method of a `Date` instance. - -### Fall-back to implementation-specific date formats - -> **Note:** This section contains implementation-specific behavior that can be inconsistent -> across implementations. - -The ECMAScript specification states: If the String does not conform to the standard -format the function may fall back to any implementation–specific heuristics or -implementation–specific parsing algorithm. Unrecognizable strings or dates containing -illegal element values in ISO formatted strings shall cause `Date.parse()` to -return [`NaN`](../NaN.mdx). - -However, invalid values in date strings not recognized as simplified ISO format as -defined by ECMA-262 may or may not result in [`NaN`](../NaN.mdx), depending on the browser -and values provided, e.g.: - -```js -// Non-ISO string with invalid date values -new Date("23/25/2014"); -``` - -will be treated as a local date of 25 November, 2015 in Firefox 30 and an invalid date -in Safari 7. - -However, if the string is recognized as an ISO format string and it contains invalid -values, it will return [`NaN`](../NaN.mdx): - -```js -// ISO string with invalid values -new Date("2014-25-23").toISOString(); -// throws "RangeError: invalid date" -``` - -SpiderMonkey's implementation-specific heuristic can be found in [`jsdate.cpp`](https://searchfox.org/mozilla-central/source/js/src/jsdate.cpp?rev=64553c483cd1#889). -The string `"10 06 2014"` is an example of a non-conforming ISO format and -thus falls back to a custom routine.

Therefore `Date` objects produced using those strings may represent different moments in time depending on the version of ECMAScript supported unless the system is set with a local time zone of UTC. This means that two date strings that appear equivalent may result in two different values depending on the format of the string that is being converted. diff --git a/documentation/versioned_docs/version-1.4.0/globals/Date/prototype/@@toPrimitive.mdx b/documentation/versioned_docs/version-1.4.0/globals/Date/prototype/@@toPrimitive.mdx deleted file mode 100644 index 0c9c5443f1..0000000000 --- a/documentation/versioned_docs/version-1.4.0/globals/Date/prototype/@@toPrimitive.mdx +++ /dev/null @@ -1,40 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Date.prototype\[Symbol.toPrimitive] - -The **`[Symbol.toPrimitive]()`** method converts a `Date` -object to a primitive value. - -## Syntax - -```js -Date()[Symbol.toPrimitive](hint) -``` - -### Return value - -The primitive value of the given `Date` object.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result.

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously).

If `isNaN(x)` returns `true`, `x` will get coerced to `NaN` and make most arithmetic expressions return `NaN` (because `NaN` propagates).

If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point.

Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

When the time zone offset is absent, -date-only forms are interpreted as a UTC time and date-time forms are interpreted as -local time. - -While time zone specifiers are used during date string parsing to interpret the -argument, the value returned is always the number of milliseconds between January 1, -1970 00:00:00 UTC and the point in time represented by the argument or `NaN`. - -Because `parse()` is a static method of `Date`, it is called as -`Date.parse()` rather than as a method of a `Date` instance. - -### Fall-back to implementation-specific date formats - -> **Note:** This section contains implementation-specific behavior that can be inconsistent -> across implementations. - -The ECMAScript specification states: If the String does not conform to the standard -format the function may fall back to any implementation–specific heuristics or -implementation–specific parsing algorithm. Unrecognizable strings or dates containing -illegal element values in ISO formatted strings shall cause `Date.parse()` to -return [`NaN`](../NaN.mdx). - -However, invalid values in date strings not recognized as simplified ISO format as -defined by ECMA-262 may or may not result in [`NaN`](../NaN.mdx), depending on the browser -and values provided, e.g.: - -```js -// Non-ISO string with invalid date values -new Date("23/25/2014"); -``` - -will be treated as a local date of 25 November, 2015 in Firefox 30 and an invalid date -in Safari 7. - -However, if the string is recognized as an ISO format string and it contains invalid -values, it will return [`NaN`](../NaN.mdx): - -```js -// ISO string with invalid values -new Date("2014-25-23").toISOString(); -// throws "RangeError: invalid date" -``` - -SpiderMonkey's implementation-specific heuristic can be found in [`jsdate.cpp`](https://searchfox.org/mozilla-central/source/js/src/jsdate.cpp?rev=64553c483cd1#889). -The string `"10 06 2014"` is an example of a non-conforming ISO format and -thus falls back to a custom routine.

Therefore `Date` objects produced using those strings may represent different moments in time depending on the version of ECMAScript supported unless the system is set with a local time zone of UTC. This means that two date strings that appear equivalent may result in two different values depending on the format of the string that is being converted. diff --git a/documentation/versioned_docs/version-1.5.0/globals/Date/prototype/@@toPrimitive.mdx b/documentation/versioned_docs/version-1.5.0/globals/Date/prototype/@@toPrimitive.mdx deleted file mode 100644 index 0c9c5443f1..0000000000 --- a/documentation/versioned_docs/version-1.5.0/globals/Date/prototype/@@toPrimitive.mdx +++ /dev/null @@ -1,40 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Date.prototype\[Symbol.toPrimitive] - -The **`[Symbol.toPrimitive]()`** method converts a `Date` -object to a primitive value. - -## Syntax - -```js -Date()[Symbol.toPrimitive](hint) -``` - -### Return value - -The primitive value of the given `Date` object.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result.

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously).

If `isNaN(x)` returns `true`, `x` will get coerced to `NaN` and make most arithmetic expressions return `NaN` (because `NaN` propagates).

If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point.

Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

When the time zone offset is absent, -date-only forms are interpreted as a UTC time and date-time forms are interpreted as -local time. - -While time zone specifiers are used during date string parsing to interpret the -argument, the value returned is always the number of milliseconds between January 1, -1970 00:00:00 UTC and the point in time represented by the argument or `NaN`. - -Because `parse()` is a static method of `Date`, it is called as -`Date.parse()` rather than as a method of a `Date` instance. - -### Fall-back to implementation-specific date formats - -> **Note:** This section contains implementation-specific behavior that can be inconsistent -> across implementations. - -The ECMAScript specification states: If the String does not conform to the standard -format the function may fall back to any implementation–specific heuristics or -implementation–specific parsing algorithm. Unrecognizable strings or dates containing -illegal element values in ISO formatted strings shall cause `Date.parse()` to -return [`NaN`](../NaN.mdx). - -However, invalid values in date strings not recognized as simplified ISO format as -defined by ECMA-262 may or may not result in [`NaN`](../NaN.mdx), depending on the browser -and values provided, e.g.: - -```js -// Non-ISO string with invalid date values -new Date("23/25/2014"); -``` - -will be treated as a local date of 25 November, 2015 in Firefox 30 and an invalid date -in Safari 7. - -However, if the string is recognized as an ISO format string and it contains invalid -values, it will return [`NaN`](../NaN.mdx): - -```js -// ISO string with invalid values -new Date("2014-25-23").toISOString(); -// throws "RangeError: invalid date" -``` - -SpiderMonkey's implementation-specific heuristic can be found in [`jsdate.cpp`](https://searchfox.org/mozilla-central/source/js/src/jsdate.cpp?rev=64553c483cd1#889). -The string `"10 06 2014"` is an example of a non-conforming ISO format and -thus falls back to a custom routine.

Therefore `Date` objects produced using those strings may represent different moments in time depending on the version of ECMAScript supported unless the system is set with a local time zone of UTC. This means that two date strings that appear equivalent may result in two different values depending on the format of the string that is being converted. diff --git a/documentation/versioned_docs/version-1.6.0/globals/Date/prototype/@@toPrimitive.mdx b/documentation/versioned_docs/version-1.6.0/globals/Date/prototype/@@toPrimitive.mdx deleted file mode 100644 index 0c9c5443f1..0000000000 --- a/documentation/versioned_docs/version-1.6.0/globals/Date/prototype/@@toPrimitive.mdx +++ /dev/null @@ -1,40 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Date.prototype\[Symbol.toPrimitive] - -The **`[Symbol.toPrimitive]()`** method converts a `Date` -object to a primitive value. - -## Syntax - -```js -Date()[Symbol.toPrimitive](hint) -``` - -### Return value - -The primitive value of the given `Date` object.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result.

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled).

In summary: - -- If a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value is passed, the returned promise is already fulfilled with that value. -- If a thenable is passed, the returned promise will adopt the state of that thenable by calling the `then` method and passing a pair of resolving functions as arguments. (But because native promises directly pass through `Promise.resolve()` without creating a wrapper, the `then` method is not called on native promises.) If the resolver function receives another thenable object, it will be resolved agin, so that the eventual fulfillment value of the promise will never be thenable. diff --git a/documentation/versioned_docs/version-1.6.0/globals/Proxy/Proxy.mdx b/documentation/versioned_docs/version-1.6.0/globals/Proxy/Proxy.mdx deleted file mode 100644 index 2b96dd6a36..0000000000 --- a/documentation/versioned_docs/version-1.6.0/globals/Proxy/Proxy.mdx +++ /dev/null @@ -1,74 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Proxy() - -The **`Proxy()`** constructor is used to create `Proxy` objects. - -## Syntax - -```js -new Proxy(target, handler) -``` - -> **Note:** `Proxy()` can only be constructed with `new`.

If `isNaN(x)` returns `true`, `x` will get coerced to `NaN` and make most arithmetic expressions return `NaN` (because `NaN` propagates).

If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point.

Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

When the time zone offset is absent, -date-only forms are interpreted as a UTC time and date-time forms are interpreted as -local time. - -While time zone specifiers are used during date string parsing to interpret the -argument, the value returned is always the number of milliseconds between January 1, -1970 00:00:00 UTC and the point in time represented by the argument or `NaN`. - -Because `parse()` is a static method of `Date`, it is called as -`Date.parse()` rather than as a method of a `Date` instance. - -### Fall-back to implementation-specific date formats - -> **Note:** This section contains implementation-specific behavior that can be inconsistent -> across implementations. - -The ECMAScript specification states: If the String does not conform to the standard -format the function may fall back to any implementation–specific heuristics or -implementation–specific parsing algorithm. Unrecognizable strings or dates containing -illegal element values in ISO formatted strings shall cause `Date.parse()` to -return [`NaN`](../NaN.mdx). - -However, invalid values in date strings not recognized as simplified ISO format as -defined by ECMA-262 may or may not result in [`NaN`](../NaN.mdx), depending on the browser -and values provided, e.g.: - -```js -// Non-ISO string with invalid date values -new Date("23/25/2014"); -``` - -will be treated as a local date of 25 November, 2015 in Firefox 30 and an invalid date -in Safari 7. - -However, if the string is recognized as an ISO format string and it contains invalid -values, it will return [`NaN`](../NaN.mdx): - -```js -// ISO string with invalid values -new Date("2014-25-23").toISOString(); -// throws "RangeError: invalid date" -``` - -SpiderMonkey's implementation-specific heuristic can be found in [`jsdate.cpp`](https://searchfox.org/mozilla-central/source/js/src/jsdate.cpp?rev=64553c483cd1#889). -The string `"10 06 2014"` is an example of a non-conforming ISO format and -thus falls back to a custom routine.

Therefore `Date` objects produced using those strings may represent different moments in time depending on the version of ECMAScript supported unless the system is set with a local time zone of UTC. This means that two date strings that appear equivalent may result in two different values depending on the format of the string that is being converted. diff --git a/documentation/versioned_docs/version-1.7.0/globals/Date/prototype/@@toPrimitive.mdx b/documentation/versioned_docs/version-1.7.0/globals/Date/prototype/@@toPrimitive.mdx deleted file mode 100644 index 0c9c5443f1..0000000000 --- a/documentation/versioned_docs/version-1.7.0/globals/Date/prototype/@@toPrimitive.mdx +++ /dev/null @@ -1,40 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Date.prototype\[Symbol.toPrimitive] - -The **`[Symbol.toPrimitive]()`** method converts a `Date` -object to a primitive value. - -## Syntax - -```js -Date()[Symbol.toPrimitive](hint) -``` - -### Return value - -The primitive value of the given `Date` object.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result.

You, the programmer, write the `executor`.

Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled).

In summary: - -- If a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value is passed, the returned promise is already fulfilled with that value. -- If a thenable is passed, the returned promise will adopt the state of that thenable by calling the `then` method and passing a pair of resolving functions as arguments. (But because native promises directly pass through `Promise.resolve()` without creating a wrapper, the `then` method is not called on native promises.) If the resolver function receives another thenable object, it will be resolved agin, so that the eventual fulfillment value of the promise will never be thenable. diff --git a/documentation/versioned_docs/version-1.7.0/globals/Proxy/Proxy.mdx b/documentation/versioned_docs/version-1.7.0/globals/Proxy/Proxy.mdx deleted file mode 100644 index 2b96dd6a36..0000000000 --- a/documentation/versioned_docs/version-1.7.0/globals/Proxy/Proxy.mdx +++ /dev/null @@ -1,74 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Proxy() - -The **`Proxy()`** constructor is used to create `Proxy` objects. - -## Syntax - -```js -new Proxy(target, handler) -``` - -> **Note:** `Proxy()` can only be constructed with `new`.

If `isNaN(x)` returns `true`, `x` will get coerced to `NaN` and make most arithmetic expressions return `NaN` (because `NaN` propagates).

If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point.

Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

When the time zone offset is absent, -date-only forms are interpreted as a UTC time and date-time forms are interpreted as -local time. - -While time zone specifiers are used during date string parsing to interpret the -argument, the value returned is always the number of milliseconds between January 1, -1970 00:00:00 UTC and the point in time represented by the argument or `NaN`. - -Because `parse()` is a static method of `Date`, it is called as -`Date.parse()` rather than as a method of a `Date` instance. - -### Fall-back to implementation-specific date formats - -> **Note:** This section contains implementation-specific behavior that can be inconsistent -> across implementations. - -The ECMAScript specification states: If the String does not conform to the standard -format the function may fall back to any implementation–specific heuristics or -implementation–specific parsing algorithm. Unrecognizable strings or dates containing -illegal element values in ISO formatted strings shall cause `Date.parse()` to -return [`NaN`](../NaN.mdx). - -However, invalid values in date strings not recognized as simplified ISO format as -defined by ECMA-262 may or may not result in [`NaN`](../NaN.mdx), depending on the browser -and values provided, e.g.: - -```js -// Non-ISO string with invalid date values -new Date("23/25/2014"); -``` - -will be treated as a local date of 25 November, 2015 in Firefox 30 and an invalid date -in Safari 7. - -However, if the string is recognized as an ISO format string and it contains invalid -values, it will return [`NaN`](../NaN.mdx): - -```js -// ISO string with invalid values -new Date("2014-25-23").toISOString(); -// throws "RangeError: invalid date" -``` - -SpiderMonkey's implementation-specific heuristic can be found in [`jsdate.cpp`](https://searchfox.org/mozilla-central/source/js/src/jsdate.cpp?rev=64553c483cd1#889). -The string `"10 06 2014"` is an example of a non-conforming ISO format and -thus falls back to a custom routine.

Therefore `Date` objects produced using those strings may represent different moments in time depending on the version of ECMAScript supported unless the system is set with a local time zone of UTC. This means that two date strings that appear equivalent may result in two different values depending on the format of the string that is being converted. diff --git a/documentation/versioned_docs/version-1.8.0/globals/Date/prototype/@@toPrimitive.mdx b/documentation/versioned_docs/version-1.8.0/globals/Date/prototype/@@toPrimitive.mdx deleted file mode 100644 index 0c9c5443f1..0000000000 --- a/documentation/versioned_docs/version-1.8.0/globals/Date/prototype/@@toPrimitive.mdx +++ /dev/null @@ -1,40 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Date.prototype\[Symbol.toPrimitive] - -The **`[Symbol.toPrimitive]()`** method converts a `Date` -object to a primitive value. - -## Syntax - -```js -Date()[Symbol.toPrimitive](hint) -``` - -### Return value - -The primitive value of the given `Date` object.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result.

You, the programmer, write the `executor`.

Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled).

In summary: - -- If a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value is passed, the returned promise is already fulfilled with that value. -- If a thenable is passed, the returned promise will adopt the state of that thenable by calling the `then` method and passing a pair of resolving functions as arguments. (But because native promises directly pass through `Promise.resolve()` without creating a wrapper, the `then` method is not called on native promises.) If the resolver function receives another thenable object, it will be resolved agin, so that the eventual fulfillment value of the promise will never be thenable. diff --git a/documentation/versioned_docs/version-1.8.0/globals/Proxy/Proxy.mdx b/documentation/versioned_docs/version-1.8.0/globals/Proxy/Proxy.mdx deleted file mode 100644 index 2b96dd6a36..0000000000 --- a/documentation/versioned_docs/version-1.8.0/globals/Proxy/Proxy.mdx +++ /dev/null @@ -1,74 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Proxy() - -The **`Proxy()`** constructor is used to create `Proxy` objects. - -## Syntax - -```js -new Proxy(target, handler) -``` - -> **Note:** `Proxy()` can only be constructed with `new`.

If `isNaN(x)` returns `true`, `x` will get coerced to `NaN` and make most arithmetic expressions return `NaN` (because `NaN` propagates).

If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point.

Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

Keep in mind that most [UNIX Timestamp](https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_16) functions are only accurate to the nearest second. - -#### Date string - -- `dateString` - - - : A string value representing a date, in a format recognized by the [`Date.parse()`](./parse.mdx) method. (The ECMA262 spec specifies a [simplified version of ISO 8601](https://tc39.es/ecma262/#sec-date-time-string-format), but other formats can be implementation-defined, which commonly include [IETF-compliant RFC 2822 timestamps](https://datatracker.ietf.org/doc/html/rfc2822#page-14).) - - > **Note:** When parsing date strings with the `Date` constructor (and `Date.parse`, they are equivalent), always make sure that the input conforms to the ISO 8601 format (`YYYY-MM-DDTHH:mm:ss.sssZ`) — the parsing behavior with other formats is implementation-defined and may not work across all browsers. Support for [RFC 2822](https://datatracker.ietf.org/doc/html/rfc2822) format strings is by convention only. A library can help if many different formats are to be accommodated. - > - > Date-only strings (e.g. `"1970-01-01"`) are treated as UTC, while date-time strings (e.g. `"1970-01-01T12:00"`) are treated as local. You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component).

In such cases, the name can be inferred, as the following few subsections demonstrate. - -One practical case where the name cannot be inferred is a function returned from another function: - -```js -function getFoo() { - return () => {}; -} -getFoo().name; // "" -``` - -### Variable declaration and method - -Variables and methods can infer the name of an anonymous function from its syntactic position. - -```js -const f = function () {}; -const object = { - someMethod: function () {} -}; - -console.log(f.name); // "f" -console.log(object.someMethod.name); // "someMethod" -``` - -The same applies to assignment: - -```js -let f; -f = () => {}; -f.name; // "f" -``` - -### Initializer and default value - -Functions in initializers (default values) of [destructuring](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment#default_value), [default parameters](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/Default_parameters), [class fields](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Classes/Public_class_fields), etc., will inherit the name of the bound identifier as their `name`. - -```js -const [f = () => {}] = []; -f.name; // "f" - -const { someMethod: m = () => {} } = {}; -m.name; // "m" - -function foo(f = () => {}) { - console.log(f.name); -} -foo(); // "f" - -class Foo { - static someMethod = () => {}; -} -Foo.someMethod.name; // someMethod -``` - -### Shorthand method - -```js -const o = { - foo() {}, -}; -o.foo.name; // "foo"; -``` - -### Bound function - -[`Function.prototype.bind()`](../../../globals/Function/prototype/bind.mdx) produces a function whose name is "bound " plus the function name. - -```js -function foo() {}; -foo.bind({}).name; // "bound foo" -``` - -### Getter and setter - -When using [`get`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/get) and [`set`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/set) accessor properties, "get" or "set" will appear in the function name. - -```js -const o = { - get foo() {}, - set foo(x) {}, -}; - -const descriptor = Object.getOwnPropertyDescriptor(o, "foo"); -descriptor.get.name; // "get foo" -descriptor.set.name; // "set foo"; -``` - -### Class - -A class's name follows the same algorithm as function declarations and expressions. - -```js -class Foo {} -Foo.name; // "Foo" -``` - -> **Warning:** JavaScript will set the function's `name` property only if a function does not have an own property called `name`. However, classes' [static members](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Classes/static) will be set as own properties of the class constructor function, and thus prevent the built-in `name` from being applied. See [an example](#telling_the_constructor_name_of_an_object) below. - -### Symbol as function name - -If a `Symbol` is used a function name and the symbol has a description, the method's name is the description in square brackets. - -```js -const sym1 = Symbol("foo"); -const sym2 = Symbol(); - -const o = { - [sym1]() {}, - [sym2]() {}, -}; - -o[sym1].name; // "[foo]" -o[sym2].name; // "[]" -``` - -### Private property - -Private fields and private methods have the hash (`#`) as part of their names. - -```js -class Foo { - #field = () => {}; - #method() {} - getNames() { - console.log(this.#field.name); - console.log(this.#method.name); - } -} - -new Foo().getNames(); -// "#field" -// "#method" -``` diff --git a/documentation/versioned_docs/version-1.9.0/globals/Function/prototype/toString.mdx b/documentation/versioned_docs/version-1.9.0/globals/Function/prototype/toString.mdx deleted file mode 100644 index c2b4572389..0000000000 --- a/documentation/versioned_docs/version-1.9.0/globals/Function/prototype/toString.mdx +++ /dev/null @@ -1,60 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Function.prototype.toString() - -The **`toString()`** method returns a string representing the source code of the specified `Function`. - -## Syntax - -```js -toString() -``` - -### Return value - -A string representing the source code of the function. - -## Description - -The `Function` object overrides the `toString()` method -inherited from `Object`; it does not inherit -[`Object.prototype.toString()`](../../../globals/Object/prototype/toString.mdx).

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result. This constraint ensures that a proper serialization (and, very likely, its accompanying deserialization) behavior is always explicitly provided by the user. -- [`undefined`](../../globals/undefined.mdx), `Function`, and `Symbol` values are not valid JSON values. If any such values are encountered during conversion, they are either omitted (when found in an object) or changed to [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null) (when found in an array). `JSON.stringify()` can return `undefined` when passing in "pure" values like `JSON.stringify(() => {})` or `JSON.stringify(undefined)`. -- The numbers [`Infinity`](../../globals/Infinity.mdx) and [`NaN`](../../globals/NaN.mdx), as well as the value [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null), are all considered `null`. (But unlike the values in the previous point, they would never be omitted.) -- Arrays are serialized as arrays (enclosed by square brackets). Only array indices between 0 and `length - 1` (inclusive) are serialized; other properties are ignored. -- For other objects: - - - All `Symbol`-keyed properties will be completely ignored, even when using the [`replacer`](#the_replacer_parameter) parameter. - - - If the value has a `toJSON()` method, it's responsible to define what data will be serialized. Instead of the object being serialized, the value returned by the `toJSON()` method when called will be serialized. `JSON.stringify()` calls `toJSON` with one parameter, the `key`, which has the same semantic as the `key` parameter of the [`replacer`](#the_replacer_parameter) function: - - - if this object is a property value, the property name - - if it is in an array, the index in the array, as a string - - if `JSON.stringify()` was directly called on this object, an empty string - - `Date` objects implement the [`toJSON()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toJSON) method which returns a string (the same as [`date.toISOString()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)). Thus, they will be stringified as strings. - - - Only [enumerable own properties](https://developer.mozilla.org/docs/Web/JavaScript/Enumerability_and_ownership_of_properties) are visited. This means [Map](../../globals/Map/Map.mdx), [Set](../../globals/Set/Set.mdx), etc. will become `"{}"`. You can use the [`replacer`](#the_replacer_parameter) parameter to serialize them to something more useful. - - Properties are visited using the same algorithm as [`Object.keys()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object/keys), which has a well-defined order and is stable across implementations. For example, `JSON.stringify` on the same object will always produce the same string, and `JSON.parse(JSON.stringify(obj))` would produce an object with the same key ordering as the original (assuming the object is completely JSON-serializable). - -### The replacer parameter - -The `replacer` parameter can be either a function or an array. - -As an array, its elements indicate the names of the properties in the object that should be included in the resulting JSON string. Only string and number values are taken into account; symbol keys are ignored. - -As a function, it takes two parameters: the `key` and the `value` being stringified. The object in which the key was found is provided as the `replacer`'s `this` context. - -The `replacer` function is called for the initial object being stringified as well, in which case the `key` is an empty string (`""`). It is then called for each property on the object or array being stringified. Array indices will be provided in its string form as `key`. The current property value will be replaced with the `replacer`'s return value for stringification. This means: - -- If you return a number, string, boolean, or `null`, that value is directly serialized and used as the property's value. (Returning a BigInt will throw as well.) -- If you return a `Function`, `Symbol`, or [`undefined`](../../globals/undefined.mdx), the property is not included in the output. -- If you return any other object, the object is recursively stringified, calling the `replacer` function on each property. - -> **Note:** When parsing JSON generated with `replacer` functions, you would likely want to use the [`reviver`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#using_the_reviver_parameter) parameter to perform the reverse operation. - -Typically, array elements' index would never shift (even when the element is an invalid value like a function, it will become `null` instead of omitted). Using the `replacer` function allows you to control the order of the array elements by returning a different array. - -### The space parameter - -The `space` parameter may be used to control spacing in the final string. - -- If it is a number, successive levels in the stringification will each be indented by this many space characters. -- If it is a string, successive levels will be indented by this string. - -Each level of indentation will never be longer than 10.

Internally, JavaScript continues to treat the number as a 64-bit float, it just performs a "round to even" on the 23rd bit of the mantissa, and sets all following mantissa bits to `0`. If the number is outside the range of a 32-bit float, `Infinity` or `-Infinity` is returned. - -Because `fround()` is a static method of `Math`, you always use it as `Math.fround()`, rather than as a method of a `Math` object you created (`Math` is not a constructor). diff --git a/documentation/versioned_docs/version-1.9.0/globals/Math/hypot.mdx b/documentation/versioned_docs/version-1.9.0/globals/Math/hypot.mdx deleted file mode 100644 index f5424c447f..0000000000 --- a/documentation/versioned_docs/version-1.9.0/globals/Math/hypot.mdx +++ /dev/null @@ -1,39 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Math.hypot() - -The **`Math.hypot()`** function returns the square root of the sum of squares of its arguments. - -## Syntax - -```js -Math.hypot() -Math.hypot(value0) -Math.hypot(value0, value1) -Math.hypot(value0, value1, /* … ,*/ valueN) -``` - -### Parameters - -- `value1`, …, `valueN` - - : Numbers. - -### Return value - -The square root of the sum of squares of the given arguments.

For example, if `o.k` is an accessor property, `Object.defineProperty(o, "k", { set: undefined })` will remove the setter, making `k` only have a getter and become readonly. If an attribute is absent from the new descriptor, the old descriptor attribute's value is kept (it won't be implicitly re-defined to `undefined`). It is possible to toggle between data and accessor property by giving a descriptor of a different "flavor".

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously). The `then` method will be called with two callbacks, which are two new functions with the exact same behaviors as the `resolveFunc` and `rejectFunc` passed to the `executor` function. If calling the `then` method throws, then the current promise is rejected with the thrown error. - -In the last case, it means code like: - -```js -new Promise((resolve, reject) => { - resolve(thenable); -}); -``` - -Is roughly equivalent to: - -```js -new Promise((resolve, reject) => { - try { - thenable.then( - (value) => resolve(value), - (reason) => reject(reason), - ); - } catch (e) { - reject(e); - } -}); -``` - -Except that in the `resolve(thenable)` case: - -1. `resolve` is called synchronously, so that calling `resolve` or `reject` again has no effect, even when the handlers attached through `anotherPromise.then()` are not called yet. -2. The `then` method is called asynchronously, so that the promise will never be instantly resolved if a thenable is passed. - -Because `resolve` is called again with whatever `thenable.then()` passes to it as `value`, the resolver function is able to flatten nested thenables, where a thenable calls its `onFulfilled` handler with another thenable.

Also, the resolved value of the promise returned by `then` will be the same as the resolved value of the promise returned by the handler. - -## Description - -The `then()` method schedules callback functions for the eventual completion of a Promise — either fulfillment or rejection. It is the primitive method of promises: the [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) protocol expects all promise-like objects to expose a `then()` method, and the [`Promise.prototype.catch`](../../../globals/Promise/prototype/catch.mdx) and [`Promise.prototype.finally`](../../../globals/Promise/prototype/finally.mdx) methods both work by invoking the object's `then()` method. - -For more information about the `onRejected` handler, see the [`Promise.prototype.catch`](../../../globals/Promise/prototype/catch.mdx) reference. - -`then()` returns a new promise object. If you call the `then()` method twice on the same promise object (instead of chaining), then this promise object will have two pairs of settlement handlers. All handlers attached to the same promise object are always called in the order they were added. Moreover, the two promises returned by each call of `then()` start separate chains and do not wait for each other's settlement. - -[Thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) objects that arise along the `then()` chain are always [resolved](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise/Promise#resolver_function) — the `onFulfilled` handler never receives a thenable object, and any thenable returned by either handler are always resolved before being passed to the next handler. This is because when constructing the new promise, the `resolve` and `reject` functions passed by the `executor` are saved, and when the current promise settles, the respective function will be called with the fulfillment value or rejection reason. The resolving logic comes from the resolver function passed by the [`Promise()`](../../../globals/Promise/Promise.mdx) constructor. - -`then()` supports subclassing, which means it can be called on instances of subclasses of `Promise`, and the result will be a promise of the subclass type. You can customize the type of the return value through the [`[Symbol.species]`](../../../globals/Promise/@@species.mdx) property. diff --git a/documentation/versioned_docs/version-1.9.0/globals/Promise/race.mdx b/documentation/versioned_docs/version-1.9.0/globals/Promise/race.mdx deleted file mode 100644 index d436d83658..0000000000 --- a/documentation/versioned_docs/version-1.9.0/globals/Promise/race.mdx +++ /dev/null @@ -1,30 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Promise.race() - -The **`Promise.race()`** method takes an iterable of promises as input and returns a single `Promise`.

Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

It runs a "reducer" callback function over all elements in the array, in ascending-index order, and accumulates them into a single value.

It is not invoked for empty slots in sparse arrays. - -Unlike other [iterative methods](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Array#iterative_methods), `reduce()` does not accept a `thisArg` argument. `callbackFn` is always called with `undefined` as `this`, which gets substituted with `globalThis` if `callbackFn` is non-strict. - -`reduce()` is a central concept in [functional programming](https://en.wikipedia.org/wiki/Functional_programming), where it's not possible to mutate any value, so in order to accumulate all values in an array, one must return a new accumulator value on every iteration. This convention propagates to JavaScript's `reduce()`: you should use [spreading](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Spread_syntax) or other copying methods where possible to create new arrays and objects as the accumulator, rather than mutating the existing one. If you decided to mutate the accumulator instead of copying it, remember to still return the modified object in the callback, or the next iteration will receive undefined. - -`reduce()` does not mutate the array on which it is called, but the function provided as `callbackFn` can. Note, however, that the length of the array is saved _before_ the first invocation of `callbackFn`. Therefore: - -- `callbackFn` will not visit any elements added beyond the array's initial length when the call to `reduce()` began. -- Changes to already-visited indexes do not cause `callbackFn` to be invoked on them again. -- If an existing, yet-unvisited element of the array is changed by `callbackFn`, its value passed to the `callbackFn` will be the value at the time that element gets visited.

If code becomes clearer when using other array methods, developers must weigh the readability tradeoff against the other benefits of using `reduce()`.

You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. - -If any parameter overflows its defined bounds, it "carries over". For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M. June 20th, 2020. - -Similarly, if any parameter underflows, it "borrows" from the higher positions. For example, `new Date(2020, 5, 0)` will return May 31st, 2020. - -- `year` - - : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year. See the [example](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date#interpretation_of_two-digit_years). -- `monthIndex` - - : Integer value representing the month, beginning with `0` for January to `11` for December. -- `day` _**optional**_ - - : Integer value representing the day of the month. The default is `1`. -- `hours` _**optional**_ - - : Integer value between `0` and `23` representing the hour of the day. Defaults to `0`. -- `minutes` _**optional**_ - - : Integer value representing the minute segment of a time. The default is `0` minutes past the hour. -- `seconds` _**optional**_ - - : Integer value representing the second segment of a time. The default is `0` seconds past the minute. -- `milliseconds` _**optional**_ - - : Integer value representing the millisecond segment of a time. The default is `0` milliseconds past the second. - -### Return value - -Calling `new Date()` (the `Date()` constructor) returns a [`Date`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date) object. If called with an invalid date string, or if the date to be constructed will have a UNIX timestamp less than `-8,640,000,000,000,000` or greater than `8,640,000,000,000,000` milliseconds, it returns a `Date` object whose [`toString()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toString) method returns the literal string `Invalid Date`. - -Calling the `Date()` function (without the `new` keyword) returns a string representation of the current date and time, exactly as `new Date().toString()` does. Any arguments given in a `Date()` function call (without the `new` keyword) are ignored; regardless of whether it's called with an invalid date string — or even called with any arbitrary object or other primitive as an argument — it always returns a string representation of the current date and time. diff --git a/documentation/versioned_docs/version-2.0.0/globals/Date/UTC.mdx b/documentation/versioned_docs/version-2.0.0/globals/Date/UTC.mdx deleted file mode 100644 index 472ad546cf..0000000000 --- a/documentation/versioned_docs/version-2.0.0/globals/Date/UTC.mdx +++ /dev/null @@ -1,84 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Date.UTC() - -The **`Date.UTC()`** method accepts parameters similar to the -`Date` constructor, but treats them as UTC.

In such cases, the name can be inferred, as the following few subsections demonstrate. - -One practical case where the name cannot be inferred is a function returned from another function: - -```js -function getFoo() { - return () => {}; -} -getFoo().name; // "" -``` - -### Variable declaration and method - -Variables and methods can infer the name of an anonymous function from its syntactic position. - -```js -const f = function () {}; -const object = { - someMethod: function () {} -}; - -console.log(f.name); // "f" -console.log(object.someMethod.name); // "someMethod" -``` - -The same applies to assignment: - -```js -let f; -f = () => {}; -f.name; // "f" -``` - -### Initializer and default value - -Functions in initializers (default values) of [destructuring](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment#default_value), [default parameters](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/Default_parameters), [class fields](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Classes/Public_class_fields), etc., will inherit the name of the bound identifier as their `name`. - -```js -const [f = () => {}] = []; -f.name; // "f" - -const { someMethod: m = () => {} } = {}; -m.name; // "m" - -function foo(f = () => {}) { - console.log(f.name); -} -foo(); // "f" - -class Foo { - static someMethod = () => {}; -} -Foo.someMethod.name; // someMethod -``` - -### Shorthand method - -```js -const o = { - foo() {}, -}; -o.foo.name; // "foo"; -``` - -### Bound function - -[`Function.prototype.bind()`](../../../globals/Function/prototype/bind.mdx) produces a function whose name is "bound " plus the function name. - -```js -function foo() {}; -foo.bind({}).name; // "bound foo" -``` - -### Getter and setter - -When using [`get`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/get) and [`set`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/set) accessor properties, "get" or "set" will appear in the function name. - -```js -const o = { - get foo() {}, - set foo(x) {}, -}; - -const descriptor = Object.getOwnPropertyDescriptor(o, "foo"); -descriptor.get.name; // "get foo" -descriptor.set.name; // "set foo"; -``` - -### Class - -A class's name follows the same algorithm as function declarations and expressions. - -```js -class Foo {} -Foo.name; // "Foo" -``` - -> **Warning:** JavaScript will set the function's `name` property only if a function does not have an own property called `name`. However, classes' [static members](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Classes/static) will be set as own properties of the class constructor function, and thus prevent the built-in `name` from being applied. See [an example](#telling_the_constructor_name_of_an_object) below. - -### Symbol as function name - -If a `Symbol` is used a function name and the symbol has a description, the method's name is the description in square brackets. - -```js -const sym1 = Symbol("foo"); -const sym2 = Symbol(); - -const o = { - [sym1]() {}, - [sym2]() {}, -}; - -o[sym1].name; // "[foo]" -o[sym2].name; // "[]" -``` - -### Private property - -Private fields and private methods have the hash (`#`) as part of their names. - -```js -class Foo { - #field = () => {}; - #method() {} - getNames() { - console.log(this.#field.name); - console.log(this.#method.name); - } -} - -new Foo().getNames(); -// "#field" -// "#method" -``` diff --git a/documentation/versioned_docs/version-2.0.0/globals/Function/prototype/toString.mdx b/documentation/versioned_docs/version-2.0.0/globals/Function/prototype/toString.mdx deleted file mode 100644 index c2b4572389..0000000000 --- a/documentation/versioned_docs/version-2.0.0/globals/Function/prototype/toString.mdx +++ /dev/null @@ -1,60 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Function.prototype.toString() - -The **`toString()`** method returns a string representing the source code of the specified `Function`. - -## Syntax - -```js -toString() -``` - -### Return value - -A string representing the source code of the function. - -## Description - -The `Function` object overrides the `toString()` method -inherited from `Object`; it does not inherit -[`Object.prototype.toString()`](../../../globals/Object/prototype/toString.mdx).

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result. This constraint ensures that a proper serialization (and, very likely, its accompanying deserialization) behavior is always explicitly provided by the user. -- [`undefined`](../../globals/undefined.mdx), `Function`, and `Symbol` values are not valid JSON values. If any such values are encountered during conversion, they are either omitted (when found in an object) or changed to [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null) (when found in an array). `JSON.stringify()` can return `undefined` when passing in "pure" values like `JSON.stringify(() => {})` or `JSON.stringify(undefined)`. -- The numbers [`Infinity`](../../globals/Infinity.mdx) and [`NaN`](../../globals/NaN.mdx), as well as the value [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null), are all considered `null`. (But unlike the values in the previous point, they would never be omitted.) -- Arrays are serialized as arrays (enclosed by square brackets). Only array indices between 0 and `length - 1` (inclusive) are serialized; other properties are ignored. -- For other objects: - - - All `Symbol`-keyed properties will be completely ignored, even when using the [`replacer`](#the_replacer_parameter) parameter. - - - If the value has a `toJSON()` method, it's responsible to define what data will be serialized. Instead of the object being serialized, the value returned by the `toJSON()` method when called will be serialized. `JSON.stringify()` calls `toJSON` with one parameter, the `key`, which has the same semantic as the `key` parameter of the [`replacer`](#the_replacer_parameter) function: - - - if this object is a property value, the property name - - if it is in an array, the index in the array, as a string - - if `JSON.stringify()` was directly called on this object, an empty string - - `Date` objects implement the [`toJSON()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toJSON) method which returns a string (the same as [`date.toISOString()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)). Thus, they will be stringified as strings. - - - Only [enumerable own properties](https://developer.mozilla.org/docs/Web/JavaScript/Enumerability_and_ownership_of_properties) are visited. This means [Map](../../globals/Map/Map.mdx), [Set](../../globals/Set/Set.mdx), etc. will become `"{}"`. You can use the [`replacer`](#the_replacer_parameter) parameter to serialize them to something more useful. - - Properties are visited using the same algorithm as [`Object.keys()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object/keys), which has a well-defined order and is stable across implementations. For example, `JSON.stringify` on the same object will always produce the same string, and `JSON.parse(JSON.stringify(obj))` would produce an object with the same key ordering as the original (assuming the object is completely JSON-serializable). - -### The replacer parameter - -The `replacer` parameter can be either a function or an array. - -As an array, its elements indicate the names of the properties in the object that should be included in the resulting JSON string. Only string and number values are taken into account; symbol keys are ignored. - -As a function, it takes two parameters: the `key` and the `value` being stringified. The object in which the key was found is provided as the `replacer`'s `this` context. - -The `replacer` function is called for the initial object being stringified as well, in which case the `key` is an empty string (`""`). It is then called for each property on the object or array being stringified. Array indices will be provided in its string form as `key`. The current property value will be replaced with the `replacer`'s return value for stringification. This means: - -- If you return a number, string, boolean, or `null`, that value is directly serialized and used as the property's value. (Returning a BigInt will throw as well.) -- If you return a `Function`, `Symbol`, or [`undefined`](../../globals/undefined.mdx), the property is not included in the output. -- If you return any other object, the object is recursively stringified, calling the `replacer` function on each property. - -> **Note:** When parsing JSON generated with `replacer` functions, you would likely want to use the [`reviver`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#using_the_reviver_parameter) parameter to perform the reverse operation. - -Typically, array elements' index would never shift (even when the element is an invalid value like a function, it will become `null` instead of omitted).

Internally, JavaScript continues to treat the number as a 64-bit float, it just performs a "round to even" on the 23rd bit of the mantissa, and sets all following mantissa bits to `0`. If the number is outside the range of a 32-bit float, `Infinity` or `-Infinity` is returned. - -Because `fround()` is a static method of `Math`, you always use it as `Math.fround()`, rather than as a method of a `Math` object you created (`Math` is not a constructor). diff --git a/documentation/versioned_docs/version-2.0.0/globals/Math/hypot.mdx b/documentation/versioned_docs/version-2.0.0/globals/Math/hypot.mdx deleted file mode 100644 index f5424c447f..0000000000 --- a/documentation/versioned_docs/version-2.0.0/globals/Math/hypot.mdx +++ /dev/null @@ -1,39 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Math.hypot() - -The **`Math.hypot()`** function returns the square root of the sum of squares of its arguments. - -## Syntax - -```js -Math.hypot() -Math.hypot(value0) -Math.hypot(value0, value1) -Math.hypot(value0, value1, /* … ,*/ valueN) -``` - -### Parameters - -- `value1`, …, `valueN` - - : Numbers. - -### Return value - -The square root of the sum of squares of the given arguments.

For example, if `o.k` is an accessor property, `Object.defineProperty(o, "k", { set: undefined })` will remove the setter, making `k` only have a getter and become readonly. If an attribute is absent from the new descriptor, the old descriptor attribute's value is kept (it won't be implicitly re-defined to `undefined`).

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously). The `then` method will be called with two callbacks, which are two new functions with the exact same behaviors as the `resolveFunc` and `rejectFunc` passed to the `executor` function. If calling the `then` method throws, then the current promise is rejected with the thrown error. - -In the last case, it means code like: - -```js -new Promise((resolve, reject) => { - resolve(thenable); -}); -``` - -Is roughly equivalent to: - -```js -new Promise((resolve, reject) => { - try { - thenable.then( - (value) => resolve(value), - (reason) => reject(reason), - ); - } catch (e) { - reject(e); - } -}); -``` - -Except that in the `resolve(thenable)` case: - -1. `resolve` is called synchronously, so that calling `resolve` or `reject` again has no effect, even when the handlers attached through `anotherPromise.then()` are not called yet. -2. The `then` method is called asynchronously, so that the promise will never be instantly resolved if a thenable is passed. - -Because `resolve` is called again with whatever `thenable.then()` passes to it as `value`, the resolver function is able to flatten nested thenables, where a thenable calls its `onFulfilled` handler with another thenable.

Also, the resolved value of the promise returned by `then` will be the same as the resolved value of the promise returned by the handler. - -## Description - -The `then()` method schedules callback functions for the eventual completion of a Promise — either fulfillment or rejection. It is the primitive method of promises: the [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) protocol expects all promise-like objects to expose a `then()` method, and the [`Promise.prototype.catch`](../../../globals/Promise/prototype/catch.mdx) and [`Promise.prototype.finally`](../../../globals/Promise/prototype/finally.mdx) methods both work by invoking the object's `then()` method. - -For more information about the `onRejected` handler, see the [`Promise.prototype.catch`](../../../globals/Promise/prototype/catch.mdx) reference. - -`then()` returns a new promise object. If you call the `then()` method twice on the same promise object (instead of chaining), then this promise object will have two pairs of settlement handlers. All handlers attached to the same promise object are always called in the order they were added. Moreover, the two promises returned by each call of `then()` start separate chains and do not wait for each other's settlement. - -[Thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) objects that arise along the `then()` chain are always [resolved](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise/Promise#resolver_function) — the `onFulfilled` handler never receives a thenable object, and any thenable returned by either handler are always resolved before being passed to the next handler. This is because when constructing the new promise, the `resolve` and `reject` functions passed by the `executor` are saved, and when the current promise settles, the respective function will be called with the fulfillment value or rejection reason. The resolving logic comes from the resolver function passed by the [`Promise()`](../../../globals/Promise/Promise.mdx) constructor. - -`then()` supports subclassing, which means it can be called on instances of subclasses of `Promise`, and the result will be a promise of the subclass type. You can customize the type of the return value through the [`[Symbol.species]`](../../../globals/Promise/@@species.mdx) property. diff --git a/documentation/versioned_docs/version-2.0.0/globals/Promise/race.mdx b/documentation/versioned_docs/version-2.0.0/globals/Promise/race.mdx deleted file mode 100644 index d436d83658..0000000000 --- a/documentation/versioned_docs/version-2.0.0/globals/Promise/race.mdx +++ /dev/null @@ -1,30 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Promise.race() - -The **`Promise.race()`** method takes an iterable of promises as input and returns a single `Promise`.

Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. - -If any parameter overflows its defined bounds, it "carries over". For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M. June 20th, 2020. - -Similarly, if any parameter underflows, it "borrows" from the higher positions. For example, `new Date(2020, 5, 0)` will return May 31st, 2020. - -- `year` - - : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year. See the [example](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date#interpretation_of_two-digit_years). -- `monthIndex` - - : Integer value representing the month, beginning with `0` for January to `11` for December. -- `day` _**optional**_ - - : Integer value representing the day of the month.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result.

The current property value will be replaced with the `replacer`'s return value for stringification.

Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value.

If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5.

Its return value becomes the return value of `replace()`. In this case the behavior of `replace()` is entirely encoded by the `@@replace` method — for example, any mention of "capturing groups" in the description below is actually functionality provided by [`RegExp.prototype[@@replace]`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/RegExp/@@replace). - -If the `pattern` is an empty string, the replacement is prepended to the start of the string. - -```js -"xxx".replace("", "_"); // "_xxx" -``` - -A regexp with the `g` flag is the only case where `replace()` replaces more than once.

If the `pattern` is a string, or if the corresponding capturing group isn't present in the regex, then the pattern will be replaced as a literal. If the group is present but isn't matched (because it's part of a disjunction), it will be replaced with an empty string. - -```js -"foo".replace(/(f)/, "$2"); -// "$2oo"; the regex doesn't have the second group - -"foo".replace("f", "$1"); -// "$1oo"; the pattern is a string, so it doesn't have any groups - -"foo".replace(/(f)|(g)/, "$2"); -// "oo"; the second group exists but isn't matched -``` - -### Specifying a function as the replacement - -You can specify a function as the second parameter. In this case, the function will be invoked after the match has been performed. The function's result (return value) will be used as the replacement string. - -> **Note:** The above-mentioned special replacement patterns do _not_ apply for strings returned from the replacer function. - -The function has the following signature: - -```js -function replacer(match, p1, p2, /* …, */ pN, offset, string, groups) { - return replacement; -} -``` - -The arguments to the function are as follows: - -- `match` - - : The matched substring. (Corresponds to `$&` above.) -- `p1, p2, …, pN` - - : The `n`th string found by a capture group (including named capturing groups), provided the first argument to `replace()` is a `RegExp` object. (Corresponds to `$1`, `$2`, etc. above.) For example, if the `pattern` is `/(\a+)(\b+)/`, then `p1` is the match for `\a+`, and `p2` is the match for `\b+`. If the group is part of a disjunction (e.g. `"abc".replace(/(a)|(b)/, replacer)`), the unmatched alternative will be `undefined`. -- `offset` - - : The offset of the matched substring within the whole string being examined. For example, if the whole string was `'abcd'`, and the matched substring was `'bc'`, then this argument will be `1`. -- `string` - - : The whole string being examined. -- `groups` - - : An object whose keys are the used group names, and whose values are the matched portions (`undefined` if not matched).

Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

Keep in mind that most [UNIX Timestamp](https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_16) functions are only accurate to the nearest second. - -#### Date string - -- `dateString` - - - : A string value representing a date, in a format recognized by the [`Date.parse()`](./parse.mdx) method. (The ECMA262 spec specifies a [simplified version of ISO 8601](https://tc39.es/ecma262/#sec-date-time-string-format), but other formats can be implementation-defined, which commonly include [IETF-compliant RFC 2822 timestamps](https://datatracker.ietf.org/doc/html/rfc2822#page-14).) - - > **Note:** When parsing date strings with the `Date` constructor (and `Date.parse`, they are equivalent), always make sure that the input conforms to the ISO 8601 format (`YYYY-MM-DDTHH:mm:ss.sssZ`) — the parsing behavior with other formats is implementation-defined and may not work across all browsers. Support for [RFC 2822](https://datatracker.ietf.org/doc/html/rfc2822) format strings is by convention only. A library can help if many different formats are to be accommodated. - > - > Date-only strings (e.g. `"1970-01-01"`) are treated as UTC, while date-time strings (e.g. `"1970-01-01T12:00"`) are treated as local. You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component).

In such cases, the name can be inferred, as the following few subsections demonstrate. - -One practical case where the name cannot be inferred is a function returned from another function: - -```js -function getFoo() { - return () => {}; -} -getFoo().name; // "" -``` - -### Variable declaration and method - -Variables and methods can infer the name of an anonymous function from its syntactic position. - -```js -const f = function () {}; -const object = { - someMethod: function () {} -}; - -console.log(f.name); // "f" -console.log(object.someMethod.name); // "someMethod" -``` - -The same applies to assignment: - -```js -let f; -f = () => {}; -f.name; // "f" -``` - -### Initializer and default value - -Functions in initializers (default values) of [destructuring](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment#default_value), [default parameters](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/Default_parameters), [class fields](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Classes/Public_class_fields), etc., will inherit the name of the bound identifier as their `name`. - -```js -const [f = () => {}] = []; -f.name; // "f" - -const { someMethod: m = () => {} } = {}; -m.name; // "m" - -function foo(f = () => {}) { - console.log(f.name); -} -foo(); // "f" - -class Foo { - static someMethod = () => {}; -} -Foo.someMethod.name; // someMethod -``` - -### Shorthand method - -```js -const o = { - foo() {}, -}; -o.foo.name; // "foo"; -``` - -### Bound function - -[`Function.prototype.bind()`](../../../globals/Function/prototype/bind.mdx) produces a function whose name is "bound " plus the function name. - -```js -function foo() {}; -foo.bind({}).name; // "bound foo" -``` - -### Getter and setter - -When using [`get`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/get) and [`set`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/set) accessor properties, "get" or "set" will appear in the function name. - -```js -const o = { - get foo() {}, - set foo(x) {}, -}; - -const descriptor = Object.getOwnPropertyDescriptor(o, "foo"); -descriptor.get.name; // "get foo" -descriptor.set.name; // "set foo"; -``` - -### Class - -A class's name follows the same algorithm as function declarations and expressions. - -```js -class Foo {} -Foo.name; // "Foo" -``` - -> **Warning:** JavaScript will set the function's `name` property only if a function does not have an own property called `name`. However, classes' [static members](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Classes/static) will be set as own properties of the class constructor function, and thus prevent the built-in `name` from being applied. See [an example](#telling_the_constructor_name_of_an_object) below. - -### Symbol as function name - -If a `Symbol` is used a function name and the symbol has a description, the method's name is the description in square brackets. - -```js -const sym1 = Symbol("foo"); -const sym2 = Symbol(); - -const o = { - [sym1]() {}, - [sym2]() {}, -}; - -o[sym1].name; // "[foo]" -o[sym2].name; // "[]" -``` - -### Private property - -Private fields and private methods have the hash (`#`) as part of their names. - -```js -class Foo { - #field = () => {}; - #method() {} - getNames() { - console.log(this.#field.name); - console.log(this.#method.name); - } -} - -new Foo().getNames(); -// "#field" -// "#method" -``` diff --git a/documentation/versioned_docs/version-2.2.0/globals/Function/prototype/toString.mdx b/documentation/versioned_docs/version-2.2.0/globals/Function/prototype/toString.mdx deleted file mode 100644 index c2b4572389..0000000000 --- a/documentation/versioned_docs/version-2.2.0/globals/Function/prototype/toString.mdx +++ /dev/null @@ -1,60 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Function.prototype.toString() - -The **`toString()`** method returns a string representing the source code of the specified `Function`. - -## Syntax - -```js -toString() -``` - -### Return value - -A string representing the source code of the function. - -## Description - -The `Function` object overrides the `toString()` method -inherited from `Object`; it does not inherit -[`Object.prototype.toString()`](../../../globals/Object/prototype/toString.mdx).

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result. This constraint ensures that a proper serialization (and, very likely, its accompanying deserialization) behavior is always explicitly provided by the user. -- [`undefined`](../../globals/undefined.mdx), `Function`, and `Symbol` values are not valid JSON values. If any such values are encountered during conversion, they are either omitted (when found in an object) or changed to [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null) (when found in an array). `JSON.stringify()` can return `undefined` when passing in "pure" values like `JSON.stringify(() => {})` or `JSON.stringify(undefined)`. -- The numbers [`Infinity`](../../globals/Infinity.mdx) and [`NaN`](../../globals/NaN.mdx), as well as the value [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null), are all considered `null`. (But unlike the values in the previous point, they would never be omitted.) -- Arrays are serialized as arrays (enclosed by square brackets). Only array indices between 0 and `length - 1` (inclusive) are serialized; other properties are ignored. -- For other objects: - - - All `Symbol`-keyed properties will be completely ignored, even when using the [`replacer`](#the_replacer_parameter) parameter. - - - If the value has a `toJSON()` method, it's responsible to define what data will be serialized. Instead of the object being serialized, the value returned by the `toJSON()` method when called will be serialized. `JSON.stringify()` calls `toJSON` with one parameter, the `key`, which has the same semantic as the `key` parameter of the [`replacer`](#the_replacer_parameter) function: - - - if this object is a property value, the property name - - if it is in an array, the index in the array, as a string - - if `JSON.stringify()` was directly called on this object, an empty string - - `Date` objects implement the [`toJSON()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toJSON) method which returns a string (the same as [`date.toISOString()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)). Thus, they will be stringified as strings. - - - Only [enumerable own properties](https://developer.mozilla.org/docs/Web/JavaScript/Enumerability_and_ownership_of_properties) are visited. This means [Map](../../globals/Map/Map.mdx), [Set](../../globals/Set/Set.mdx), etc. will become `"{}"`. You can use the [`replacer`](#the_replacer_parameter) parameter to serialize them to something more useful. - - Properties are visited using the same algorithm as [`Object.keys()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object/keys), which has a well-defined order and is stable across implementations. For example, `JSON.stringify` on the same object will always produce the same string, and `JSON.parse(JSON.stringify(obj))` would produce an object with the same key ordering as the original (assuming the object is completely JSON-serializable). - -### The replacer parameter - -The `replacer` parameter can be either a function or an array. - -As an array, its elements indicate the names of the properties in the object that should be included in the resulting JSON string. Only string and number values are taken into account; symbol keys are ignored. - -As a function, it takes two parameters: the `key` and the `value` being stringified. The object in which the key was found is provided as the `replacer`'s `this` context. - -The `replacer` function is called for the initial object being stringified as well, in which case the `key` is an empty string (`""`). It is then called for each property on the object or array being stringified. Array indices will be provided in its string form as `key`. The current property value will be replaced with the `replacer`'s return value for stringification. This means: - -- If you return a number, string, boolean, or `null`, that value is directly serialized and used as the property's value. (Returning a BigInt will throw as well.) -- If you return a `Function`, `Symbol`, or [`undefined`](../../globals/undefined.mdx), the property is not included in the output. -- If you return any other object, the object is recursively stringified, calling the `replacer` function on each property. - -> **Note:** When parsing JSON generated with `replacer` functions, you would likely want to use the [`reviver`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#using_the_reviver_parameter) parameter to perform the reverse operation. - -Typically, array elements' index would never shift (even when the element is an invalid value like a function, it will become `null` instead of omitted).

Internally, JavaScript continues to treat the number as a 64-bit float, it just performs a "round to even" on the 23rd bit of the mantissa, and sets all following mantissa bits to `0`. If the number is outside the range of a 32-bit float, `Infinity` or `-Infinity` is returned. - -Because `fround()` is a static method of `Math`, you always use it as `Math.fround()`, rather than as a method of a `Math` object you created (`Math` is not a constructor). diff --git a/documentation/versioned_docs/version-2.2.0/globals/Math/hypot.mdx b/documentation/versioned_docs/version-2.2.0/globals/Math/hypot.mdx deleted file mode 100644 index f5424c447f..0000000000 --- a/documentation/versioned_docs/version-2.2.0/globals/Math/hypot.mdx +++ /dev/null @@ -1,39 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Math.hypot() - -The **`Math.hypot()`** function returns the square root of the sum of squares of its arguments. - -## Syntax - -```js -Math.hypot() -Math.hypot(value0) -Math.hypot(value0, value1) -Math.hypot(value0, value1, /* … ,*/ valueN) -``` - -### Parameters - -- `value1`, …, `valueN` - - : Numbers. - -### Return value - -The square root of the sum of squares of the given arguments.

For example, if `o.k` is an accessor property, `Object.defineProperty(o, "k", { set: undefined })` will remove the setter, making `k` only have a getter and become readonly. If an attribute is absent from the new descriptor, the old descriptor attribute's value is kept (it won't be implicitly re-defined to `undefined`). It is possible to toggle between data and accessor property by giving a descriptor of a different "flavor".

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously). The `then` method will be called with two callbacks, which are two new functions with the exact same behaviors as the `resolveFunc` and `rejectFunc` passed to the `executor` function. If calling the `then` method throws, then the current promise is rejected with the thrown error. - -In the last case, it means code like: - -```js -new Promise((resolve, reject) => { - resolve(thenable); -}); -``` - -Is roughly equivalent to: - -```js -new Promise((resolve, reject) => { - try { - thenable.then( - (value) => resolve(value), - (reason) => reject(reason), - ); - } catch (e) { - reject(e); - } -}); -``` - -Except that in the `resolve(thenable)` case: - -1. `resolve` is called synchronously, so that calling `resolve` or `reject` again has no effect, even when the handlers attached through `anotherPromise.then()` are not called yet. -2. The `then` method is called asynchronously, so that the promise will never be instantly resolved if a thenable is passed. - -Because `resolve` is called again with whatever `thenable.then()` passes to it as `value`, the resolver function is able to flatten nested thenables, where a thenable calls its `onFulfilled` handler with another thenable.

Also, the resolved value of the promise returned by `then` will be the same as the resolved value of the promise returned by the handler. - -## Description - -The `then()` method schedules callback functions for the eventual completion of a Promise — either fulfillment or rejection. It is the primitive method of promises: the [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) protocol expects all promise-like objects to expose a `then()` method, and the [`Promise.prototype.catch`](../../../globals/Promise/prototype/catch.mdx) and [`Promise.prototype.finally`](../../../globals/Promise/prototype/finally.mdx) methods both work by invoking the object's `then()` method. - -For more information about the `onRejected` handler, see the [`Promise.prototype.catch`](../../../globals/Promise/prototype/catch.mdx) reference. - -`then()` returns a new promise object. If you call the `then()` method twice on the same promise object (instead of chaining), then this promise object will have two pairs of settlement handlers. All handlers attached to the same promise object are always called in the order they were added. Moreover, the two promises returned by each call of `then()` start separate chains and do not wait for each other's settlement. - -[Thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) objects that arise along the `then()` chain are always [resolved](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise/Promise#resolver_function) — the `onFulfilled` handler never receives a thenable object, and any thenable returned by either handler are always resolved before being passed to the next handler. This is because when constructing the new promise, the `resolve` and `reject` functions passed by the `executor` are saved, and when the current promise settles, the respective function will be called with the fulfillment value or rejection reason. The resolving logic comes from the resolver function passed by the [`Promise()`](../../../globals/Promise/Promise.mdx) constructor. - -`then()` supports subclassing, which means it can be called on instances of subclasses of `Promise`, and the result will be a promise of the subclass type. You can customize the type of the return value through the [`[Symbol.species]`](../../../globals/Promise/@@species.mdx) property. diff --git a/documentation/versioned_docs/version-2.2.0/globals/Promise/race.mdx b/documentation/versioned_docs/version-2.2.0/globals/Promise/race.mdx deleted file mode 100644 index d436d83658..0000000000 --- a/documentation/versioned_docs/version-2.2.0/globals/Promise/race.mdx +++ /dev/null @@ -1,30 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Promise.race() - -The **`Promise.race()`** method takes an iterable of promises as input and returns a single `Promise`.

For example, `parseInt("42")` and `parseFloat("42")` would return the same value: a `Number` 42. - -## Description - -The `parseInt` function converts its first argument to a string, parses that string, then returns an integer or `NaN`. - -If not `NaN`, the return value will be the integer that is the first argument taken as a number in the specified `radix`.

If the input `string`, with leading whitespace and possible `+`/`-` signs removed, begins with `0x` or `0X` (a zero, followed by lowercase or uppercase X), `radix` is assumed to be `16` and the rest of the string is parsed as a hexadecimal number. -2. If the input `string` begins with any other value, the radix is `10` (decimal). - -> **Note:** Other prefixes like `0b`, which are valid in [number literals](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Lexical_grammar#binary), are treated as normal digits by `parseInt()`. `parseInt()` does _not_ treat strings beginning with a `0` character as octal values either. The only prefix that `parseInt()` recognizes is `0x` or `0X` for hexadecimal values — everything else is parsed as a decimal value if `radix` is missing. - -If the radix is `16`, `parseInt()` allows the string to be optionally prefixed by `0x` or `0X` after the optional sign character (`+`/`-`). - -If the radix value (coerced if necessary) is not in range \[2, 36] (inclusive) `parseInt` returns `NaN`. - -For radices above `10`, letters of the English alphabet indicate numerals greater than `9`. For example, for hexadecimal numbers (base `16`), `A` through `F` are used. The letters are case-insensitive. - -`parseInt` understands exactly two signs: `+` for positive, and `-` for negative. It is done as an initial step in the parsing after whitespace is removed. If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point. For example, although `1e3` technically encodes an integer (and will be correctly parsed to the integer `1000` by [`parseFloat()`](./parseFloat.mdx), `parseInt("1e3", 10)` returns `1`, because `e` is not a valid numeral in base 10. Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

(The ECMA262 spec specifies a [simplified version of ISO 8601](https://tc39.es/ecma262/#sec-date-time-string-format), but other formats can be implementation-defined, which commonly include [IETF-compliant RFC 2822 timestamps](https://datatracker.ietf.org/doc/html/rfc2822#page-14).) - - > **Note:** When parsing date strings with the `Date` constructor (and `Date.parse`, they are equivalent), always make sure that the input conforms to the ISO 8601 format (`YYYY-MM-DDTHH:mm:ss.sssZ`) — the parsing behavior with other formats is implementation-defined and may not work across all browsers.

You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. - -If any parameter overflows its defined bounds, it "carries over". For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M. June 20th, 2020. - -Similarly, if any parameter underflows, it "borrows" from the higher positions. For example, `new Date(2020, 5, 0)` will return May 31st, 2020. - -- `year` - - : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year. See the [example](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date#interpretation_of_two-digit_years). -- `monthIndex` - - : Integer value representing the month, beginning with `0` for January to `11` for December. -- `day` _**optional**_ - - : Integer value representing the day of the month.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result.

It is then called for each property on the object or array being stringified. Array indices will be provided in its string form as `key`. The current property value will be replaced with the `replacer`'s return value for stringification. This means: - -- If you return a number, string, boolean, or `null`, that value is directly serialized and used as the property's value.

Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value.

If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5.

Its return value becomes the return value of `replace()`. In this case the behavior of `replace()` is entirely encoded by the `@@replace` method — for example, any mention of "capturing groups" in the description below is actually functionality provided by [`RegExp.prototype[@@replace]`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/RegExp/@@replace). - -If the `pattern` is an empty string, the replacement is prepended to the start of the string. - -```js -"xxx".replace("", "_"); // "_xxx" -``` - -A regexp with the `g` flag is the only case where `replace()` replaces more than once.

If the `pattern` is a string, or if the corresponding capturing group isn't present in the regex, then the pattern will be replaced as a literal. If the group is present but isn't matched (because it's part of a disjunction), it will be replaced with an empty string. - -```js -"foo".replace(/(f)/, "$2"); -// "$2oo"; the regex doesn't have the second group - -"foo".replace("f", "$1"); -// "$1oo"; the pattern is a string, so it doesn't have any groups - -"foo".replace(/(f)|(g)/, "$2"); -// "oo"; the second group exists but isn't matched -``` - -### Specifying a function as the replacement - -You can specify a function as the second parameter. In this case, the function will be invoked after the match has been performed. The function's result (return value) will be used as the replacement string. - -> **Note:** The above-mentioned special replacement patterns do _not_ apply for strings returned from the replacer function. - -The function has the following signature: - -```js -function replacer(match, p1, p2, /* …, */ pN, offset, string, groups) { - return replacement; -} -``` - -The arguments to the function are as follows: - -- `match` - - : The matched substring. (Corresponds to `$&` above.) -- `p1, p2, …, pN` - - : The `n`th string found by a capture group (including named capturing groups), provided the first argument to `replace()` is a `RegExp` object. (Corresponds to `$1`, `$2`, etc. above.) For example, if the `pattern` is `/(\a+)(\b+)/`, then `p1` is the match for `\a+`, and `p2` is the match for `\b+`. If the group is part of a disjunction (e.g. `"abc".replace(/(a)|(b)/, replacer)`), the unmatched alternative will be `undefined`. -- `offset` - - : The offset of the matched substring within the whole string being examined. For example, if the whole string was `'abcd'`, and the matched substring was `'bc'`, then this argument will be `1`. -- `string` - - : The whole string being examined. -- `groups` - - : An object whose keys are the used group names, and whose values are the matched portions (`undefined` if not matched).

Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix.

Keep in mind that most [UNIX Timestamp](https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_16) functions are only accurate to the nearest second. - -#### Date string - -- `dateString` - - - : A string value representing a date, in a format recognized by the [`Date.parse()`](./parse.mdx) method. (The ECMA262 spec specifies a [simplified version of ISO 8601](https://tc39.es/ecma262/#sec-date-time-string-format), but other formats can be implementation-defined, which commonly include [IETF-compliant RFC 2822 timestamps](https://datatracker.ietf.org/doc/html/rfc2822#page-14).) - - > **Note:** When parsing date strings with the `Date` constructor (and `Date.parse`, they are equivalent), always make sure that the input conforms to the ISO 8601 format (`YYYY-MM-DDTHH:mm:ss.sssZ`) — the parsing behavior with other formats is implementation-defined and may not work across all browsers. Support for [RFC 2822](https://datatracker.ietf.org/doc/html/rfc2822) format strings is by convention only. A library can help if many different formats are to be accommodated. - > - > Date-only strings (e.g. `"1970-01-01"`) are treated as UTC, while date-time strings (e.g. `"1970-01-01T12:00"`) are treated as local. You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component).

In such cases, the name can be inferred, as the following few subsections demonstrate. - -One practical case where the name cannot be inferred is a function returned from another function: - -```js -function getFoo() { - return () => {}; -} -getFoo().name; // "" -``` - -### Variable declaration and method - -Variables and methods can infer the name of an anonymous function from its syntactic position. - -```js -const f = function () {}; -const object = { - someMethod: function () {} -}; - -console.log(f.name); // "f" -console.log(object.someMethod.name); // "someMethod" -``` - -The same applies to assignment: - -```js -let f; -f = () => {}; -f.name; // "f" -``` - -### Initializer and default value - -Functions in initializers (default values) of [destructuring](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment#default_value), [default parameters](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/Default_parameters), [class fields](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Classes/Public_class_fields), etc., will inherit the name of the bound identifier as their `name`. - -```js -const [f = () => {}] = []; -f.name; // "f" - -const { someMethod: m = () => {} } = {}; -m.name; // "m" - -function foo(f = () => {}) { - console.log(f.name); -} -foo(); // "f" - -class Foo { - static someMethod = () => {}; -} -Foo.someMethod.name; // someMethod -``` - -### Shorthand method - -```js -const o = { - foo() {}, -}; -o.foo.name; // "foo"; -``` - -### Bound function - -[`Function.prototype.bind()`](../../../globals/Function/prototype/bind.mdx) produces a function whose name is "bound " plus the function name. - -```js -function foo() {}; -foo.bind({}).name; // "bound foo" -``` - -### Getter and setter - -When using [`get`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/get) and [`set`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/set) accessor properties, "get" or "set" will appear in the function name. - -```js -const o = { - get foo() {}, - set foo(x) {}, -}; - -const descriptor = Object.getOwnPropertyDescriptor(o, "foo"); -descriptor.get.name; // "get foo" -descriptor.set.name; // "set foo"; -``` - -### Class - -A class's name follows the same algorithm as function declarations and expressions. - -```js -class Foo {} -Foo.name; // "Foo" -``` - -> **Warning:** JavaScript will set the function's `name` property only if a function does not have an own property called `name`. However, classes' [static members](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Classes/static) will be set as own properties of the class constructor function, and thus prevent the built-in `name` from being applied. See [an example](#telling_the_constructor_name_of_an_object) below. - -### Symbol as function name - -If a `Symbol` is used a function name and the symbol has a description, the method's name is the description in square brackets. - -```js -const sym1 = Symbol("foo"); -const sym2 = Symbol(); - -const o = { - [sym1]() {}, - [sym2]() {}, -}; - -o[sym1].name; // "[foo]" -o[sym2].name; // "[]" -``` - -### Private property - -Private fields and private methods have the hash (`#`) as part of their names. - -```js -class Foo { - #field = () => {}; - #method() {} - getNames() { - console.log(this.#field.name); - console.log(this.#method.name); - } -} - -new Foo().getNames(); -// "#field" -// "#method" -``` diff --git a/documentation/versioned_docs/version-2.4.0/globals/Function/prototype/toString.mdx b/documentation/versioned_docs/version-2.4.0/globals/Function/prototype/toString.mdx deleted file mode 100644 index c2b4572389..0000000000 --- a/documentation/versioned_docs/version-2.4.0/globals/Function/prototype/toString.mdx +++ /dev/null @@ -1,60 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Function.prototype.toString() - -The **`toString()`** method returns a string representing the source code of the specified `Function`. - -## Syntax - -```js -toString() -``` - -### Return value - -A string representing the source code of the function. - -## Description - -The `Function` object overrides the `toString()` method -inherited from `Object`; it does not inherit -[`Object.prototype.toString()`](../../../globals/Object/prototype/toString.mdx).

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result. This constraint ensures that a proper serialization (and, very likely, its accompanying deserialization) behavior is always explicitly provided by the user. -- [`undefined`](../../globals/undefined.mdx), `Function`, and `Symbol` values are not valid JSON values. If any such values are encountered during conversion, they are either omitted (when found in an object) or changed to [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null) (when found in an array). `JSON.stringify()` can return `undefined` when passing in "pure" values like `JSON.stringify(() => {})` or `JSON.stringify(undefined)`. -- The numbers [`Infinity`](../../globals/Infinity.mdx) and [`NaN`](../../globals/NaN.mdx), as well as the value [`null`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/null), are all considered `null`. (But unlike the values in the previous point, they would never be omitted.) -- Arrays are serialized as arrays (enclosed by square brackets). Only array indices between 0 and `length - 1` (inclusive) are serialized; other properties are ignored. -- For other objects: - - - All `Symbol`-keyed properties will be completely ignored, even when using the [`replacer`](#the_replacer_parameter) parameter. - - - If the value has a `toJSON()` method, it's responsible to define what data will be serialized. Instead of the object being serialized, the value returned by the `toJSON()` method when called will be serialized. `JSON.stringify()` calls `toJSON` with one parameter, the `key`, which has the same semantic as the `key` parameter of the [`replacer`](#the_replacer_parameter) function: - - - if this object is a property value, the property name - - if it is in an array, the index in the array, as a string - - if `JSON.stringify()` was directly called on this object, an empty string - - `Date` objects implement the [`toJSON()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toJSON) method which returns a string (the same as [`date.toISOString()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)). Thus, they will be stringified as strings. - - - Only [enumerable own properties](https://developer.mozilla.org/docs/Web/JavaScript/Enumerability_and_ownership_of_properties) are visited. This means [Map](../../globals/Map/Map.mdx), [Set](../../globals/Set/Set.mdx), etc. will become `"{}"`. You can use the [`replacer`](#the_replacer_parameter) parameter to serialize them to something more useful. - - Properties are visited using the same algorithm as [`Object.keys()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object/keys), which has a well-defined order and is stable across implementations. For example, `JSON.stringify` on the same object will always produce the same string, and `JSON.parse(JSON.stringify(obj))` would produce an object with the same key ordering as the original (assuming the object is completely JSON-serializable). - -### The replacer parameter - -The `replacer` parameter can be either a function or an array. - -As an array, its elements indicate the names of the properties in the object that should be included in the resulting JSON string. Only string and number values are taken into account; symbol keys are ignored. - -As a function, it takes two parameters: the `key` and the `value` being stringified. The object in which the key was found is provided as the `replacer`'s `this` context. - -The `replacer` function is called for the initial object being stringified as well, in which case the `key` is an empty string (`""`). It is then called for each property on the object or array being stringified. Array indices will be provided in its string form as `key`. The current property value will be replaced with the `replacer`'s return value for stringification. This means: - -- If you return a number, string, boolean, or `null`, that value is directly serialized and used as the property's value. (Returning a BigInt will throw as well.) -- If you return a `Function`, `Symbol`, or [`undefined`](../../globals/undefined.mdx), the property is not included in the output. -- If you return any other object, the object is recursively stringified, calling the `replacer` function on each property. - -> **Note:** When parsing JSON generated with `replacer` functions, you would likely want to use the [`reviver`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#using_the_reviver_parameter) parameter to perform the reverse operation. - -Typically, array elements' index would never shift (even when the element is an invalid value like a function, it will become `null` instead of omitted).

Internally, JavaScript continues to treat the number as a 64-bit float, it just performs a "round to even" on the 23rd bit of the mantissa, and sets all following mantissa bits to `0`. If the number is outside the range of a 32-bit float, `Infinity` or `-Infinity` is returned. - -Because `fround()` is a static method of `Math`, you always use it as `Math.fround()`, rather than as a method of a `Math` object you created (`Math` is not a constructor). diff --git a/documentation/versioned_docs/version-2.4.0/globals/Math/hypot.mdx b/documentation/versioned_docs/version-2.4.0/globals/Math/hypot.mdx deleted file mode 100644 index f5424c447f..0000000000 --- a/documentation/versioned_docs/version-2.4.0/globals/Math/hypot.mdx +++ /dev/null @@ -1,39 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Math.hypot() - -The **`Math.hypot()`** function returns the square root of the sum of squares of its arguments. - -## Syntax - -```js -Math.hypot() -Math.hypot(value0) -Math.hypot(value0, value1) -Math.hypot(value0, value1, /* … ,*/ valueN) -``` - -### Parameters - -- `value1`, …, `valueN` - - : Numbers. - -### Return value - -The square root of the sum of squares of the given arguments.

For example, if `o.k` is an accessor property, `Object.defineProperty(o, "k", { set: undefined })` will remove the setter, making `k` only have a getter and become readonly. If an attribute is absent from the new descriptor, the old descriptor attribute's value is kept (it won't be implicitly re-defined to `undefined`). It is possible to toggle between data and accessor property by giving a descriptor of a different "flavor".

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously). The `then` method will be called with two callbacks, which are two new functions with the exact same behaviors as the `resolveFunc` and `rejectFunc` passed to the `executor` function. If calling the `then` method throws, then the current promise is rejected with the thrown error. - -In the last case, it means code like: - -```js -new Promise((resolve, reject) => { - resolve(thenable); -}); -``` - -Is roughly equivalent to: - -```js -new Promise((resolve, reject) => { - try { - thenable.then( - (value) => resolve(value), - (reason) => reject(reason), - ); - } catch (e) { - reject(e); - } -}); -``` - -Except that in the `resolve(thenable)` case: - -1. `resolve` is called synchronously, so that calling `resolve` or `reject` again has no effect, even when the handlers attached through `anotherPromise.then()` are not called yet. -2. The `then` method is called asynchronously, so that the promise will never be instantly resolved if a thenable is passed. - -Because `resolve` is called again with whatever `thenable.then()` passes to it as `value`, the resolver function is able to flatten nested thenables, where a thenable calls its `onFulfilled` handler with another thenable.

Also, the resolved value of the promise returned by `then` will be the same as the resolved value of the promise returned by the handler. - -## Description - -The `then()` method schedules callback functions for the eventual completion of a Promise — either fulfillment or rejection. It is the primitive method of promises: the [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) protocol expects all promise-like objects to expose a `then()` method, and the [`Promise.prototype.catch`](../../../globals/Promise/prototype/catch.mdx) and [`Promise.prototype.finally`](../../../globals/Promise/prototype/finally.mdx) methods both work by invoking the object's `then()` method. - -For more information about the `onRejected` handler, see the [`Promise.prototype.catch`](../../../globals/Promise/prototype/catch.mdx) reference. - -`then()` returns a new promise object. If you call the `then()` method twice on the same promise object (instead of chaining), then this promise object will have two pairs of settlement handlers. All handlers attached to the same promise object are always called in the order they were added. Moreover, the two promises returned by each call of `then()` start separate chains and do not wait for each other's settlement. - -[Thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) objects that arise along the `then()` chain are always [resolved](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise/Promise#resolver_function) — the `onFulfilled` handler never receives a thenable object, and any thenable returned by either handler are always resolved before being passed to the next handler. This is because when constructing the new promise, the `resolve` and `reject` functions passed by the `executor` are saved, and when the current promise settles, the respective function will be called with the fulfillment value or rejection reason. The resolving logic comes from the resolver function passed by the [`Promise()`](../../../globals/Promise/Promise.mdx) constructor. - -`then()` supports subclassing, which means it can be called on instances of subclasses of `Promise`, and the result will be a promise of the subclass type. You can customize the type of the return value through the [`[Symbol.species]`](../../../globals/Promise/@@species.mdx) property. diff --git a/documentation/versioned_docs/version-2.4.0/globals/Promise/race.mdx b/documentation/versioned_docs/version-2.4.0/globals/Promise/race.mdx deleted file mode 100644 index d436d83658..0000000000 --- a/documentation/versioned_docs/version-2.4.0/globals/Promise/race.mdx +++ /dev/null @@ -1,30 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Promise.race() - -The **`Promise.race()`** method takes an iterable of promises as input and returns a single `Promise`.

For example, `parseInt("42")` and `parseFloat("42")` would return the same value: a `Number` 42. - -## Description - -The `parseInt` function converts its first argument to a string, parses that string, then returns an integer or `NaN`. - -If not `NaN`, the return value will be the integer that is the first argument taken as a number in the specified `radix`. (For example, a `radix` of `10` converts from a decimal number, `8` converts from octal, `16` from hexadecimal, and so on.) - -The `radix` argument is converted to a number. If it's unprovided, or if the value becomes 0, `NaN` or `Infinity` (`undefined` is coerced to `NaN`), JavaScript assumes the following: - -1. If the input `string`, with leading whitespace and possible `+`/`-` signs removed, begins with `0x` or `0X` (a zero, followed by lowercase or uppercase X), `radix` is assumed to be `16` and the rest of the string is parsed as a hexadecimal number. -2. If the input `string` begins with any other value, the radix is `10` (decimal). - -> **Note:** Other prefixes like `0b`, which are valid in [number literals](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Lexical_grammar#binary), are treated as normal digits by `parseInt()`. `parseInt()` does _not_ treat strings beginning with a `0` character as octal values either. The only prefix that `parseInt()` recognizes is `0x` or `0X` for hexadecimal values — everything else is parsed as a decimal value if `radix` is missing. - -If the radix is `16`, `parseInt()` allows the string to be optionally prefixed by `0x` or `0X` after the optional sign character (`+`/`-`). - -If the radix value (coerced if necessary) is not in range \[2, 36] (inclusive) `parseInt` returns `NaN`. - -For radices above `10`, letters of the English alphabet indicate numerals greater than `9`. For example, for hexadecimal numbers (base `16`), `A` through `F` are used. The letters are case-insensitive. - -`parseInt` understands exactly two signs: `+` for positive, and `-` for negative. It is done as an initial step in the parsing after whitespace is removed. If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point. For example, although `1e3` technically encodes an integer (and will be correctly parsed to the integer `1000` by [`parseFloat()`](./parseFloat.mdx), `parseInt("1e3", 10)` returns `1`, because `e` is not a valid numeral in base 10. Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

(The ECMA262 spec specifies a [simplified version of ISO 8601](https://tc39.es/ecma262/#sec-date-time-string-format), but other formats can be implementation-defined, which commonly include [IETF-compliant RFC 2822 timestamps](https://datatracker.ietf.org/doc/html/rfc2822#page-14).) - - > **Note:** When parsing date strings with the `Date` constructor (and `Date.parse`, they are equivalent), always make sure that the input conforms to the ISO 8601 format (`YYYY-MM-DDTHH:mm:ss.sssZ`) — the parsing behavior with other formats is implementation-defined and may not work across all browsers.

You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. - -If any parameter overflows its defined bounds, it "carries over". For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M. June 20th, 2020. - -Similarly, if any parameter underflows, it "borrows" from the higher positions. For example, `new Date(2020, 5, 0)` will return May 31st, 2020. - -- `year` - - : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year. See the [example](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date#interpretation_of_two-digit_years). -- `monthIndex` - - : Integer value representing the month, beginning with `0` for January to `11` for December. -- `day` _**optional**_ - - : Integer value representing the day of the month. The default is `1`. -- `hours` _**optional**_ - - : Integer value between `0` and `23` representing the hour of the day.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result.

For example, `JSON.stringify` on the same object will always produce the same string, and `JSON.parse(JSON.stringify(obj))` would produce an object with the same key ordering as the original (assuming the object is completely JSON-serializable). - -### The replacer parameter - -The `replacer` parameter can be either a function or an array. - -As an array, its elements indicate the names of the properties in the object that should be included in the resulting JSON string.

It is then called for each property on the object or array being stringified. Array indices will be provided in its string form as `key`. The current property value will be replaced with the `replacer`'s return value for stringification. This means: - -- If you return a number, string, boolean, or `null`, that value is directly serialized and used as the property's value.

Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value.

If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5.

If the `pattern` is a string, or if the corresponding capturing group isn't present in the regex, then the pattern will be replaced as a literal. If the group is present but isn't matched (because it's part of a disjunction), it will be replaced with an empty string. - -```js -"foo".replace(/(f)/, "$2"); -// "$2oo"; the regex doesn't have the second group - -"foo".replace("f", "$1"); -// "$1oo"; the pattern is a string, so it doesn't have any groups - -"foo".replace(/(f)|(g)/, "$2"); -// "oo"; the second group exists but isn't matched -``` - -### Specifying a function as the replacement - -You can specify a function as the second parameter. In this case, the function will be invoked after the match has been performed. The function's result (return value) will be used as the replacement string. - -> **Note:** The above-mentioned special replacement patterns do _not_ apply for strings returned from the replacer function. - -The function has the following signature: - -```js -function replacer(match, p1, p2, /* …, */ pN, offset, string, groups) { - return replacement; -} -``` - -The arguments to the function are as follows: - -- `match` - - : The matched substring. (Corresponds to `$&` above.) -- `p1, p2, …, pN` - - : The `n`th string found by a capture group (including named capturing groups), provided the first argument to `replace()` is a `RegExp` object. (Corresponds to `$1`, `$2`, etc. above.) For example, if the `pattern` is `/(\a+)(\b+)/`, then `p1` is the match for `\a+`, and `p2` is the match for `\b+`. If the group is part of a disjunction (e.g. `"abc".replace(/(a)|(b)/, replacer)`), the unmatched alternative will be `undefined`. -- `offset` - - : The offset of the matched substring within the whole string being examined. For example, if the whole string was `'abcd'`, and the matched substring was `'bc'`, then this argument will be `1`. -- `string` - - : The whole string being examined. -- `groups` - - : An object whose keys are the used group names, and whose values are the matched portions (`undefined` if not matched).

For example, the URL `https://example.org/articles/this-that-other-outre-collection` has `this-that-other-outre-collection` as its slug. - -Some systems use the `;` and `=` characters to delimit parameters and parameter values applicable to a path segment. For example, with the URL `https://example.org/users;id=42/tasks;state=open?sort=modified`, a system might extract and use the path segment parameters `id=42` and `state=open` from the path segments `users;id=42` and `tasks;state=open`. - -## Value - -A string. diff --git a/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/port.mdx b/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/port.mdx deleted file mode 100644 index 8cea5bef05..0000000000 --- a/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/port.mdx +++ /dev/null @@ -1,16 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# URL.port - -The **`port`** property of the `URL` interface is -a string containing the port number of the URL. - -> **Note:** If an input string passed to the `URL()` constructor doesn't contain an explicit port number (e.g., `https://localhost`) or contains a port number that's the default port number corresponding to the protocol part of the input string (e.g., `https://localhost:443`), then in the `URL` object the constructor returns, the value of the port property will be the empty string: `''`. - -## Value - -A string. diff --git a/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/protocol.mdx b/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/protocol.mdx deleted file mode 100644 index 71a10df689..0000000000 --- a/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/protocol.mdx +++ /dev/null @@ -1,15 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# URL.protocol - -The **`protocol`** property of the `URL` interface -is a string representing the protocol scheme of the URL, including the -final `':'`. - -## Value - -A string. diff --git a/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/search.mdx b/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/search.mdx deleted file mode 100644 index 2461187aa7..0000000000 --- a/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/search.mdx +++ /dev/null @@ -1,16 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# URL.search - -The **`search`** property of the `URL` interface -is a search string, also called a _query string_, that is a -string containing a `'?'` followed by the parameters of the -URL. - -## Value - -A string. diff --git a/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/searchParams.mdx b/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/searchParams.mdx deleted file mode 100644 index 0aea9464d8..0000000000 --- a/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/searchParams.mdx +++ /dev/null @@ -1,15 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# URL.searchParams - -The **`searchParams`** readonly property of the -`URL` interface returns a `URLSearchParams` object allowing -access to the `GET` decoded query arguments contained in the URL. - -## Value - -A `URLSearchParams` object. diff --git a/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/toJSON.mdx b/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/toJSON.mdx deleted file mode 100644 index 62d7c77dff..0000000000 --- a/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/toJSON.mdx +++ /dev/null @@ -1,26 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# URL.toJSON() - -The **`toJSON()`** method of the `URL` interface -returns a string containing a serialized version of the URL, -although in practice it seems to have the same effect as -`URL.toString()`. - -## Syntax - -```js -toJSON() -``` - -### Parameters - -None. - -### Return value - -A string. diff --git a/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/toString.mdx b/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/toString.mdx deleted file mode 100644 index 66dd311fe9..0000000000 --- a/documentation/versioned_docs/version-3.0.0/globals/URL/prototype/toString.mdx +++ /dev/null @@ -1,25 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# URL.toString() - -The **`URL.toString()`** method returns a -string containing the whole URL.

If `isNaN(x)` returns `true`, `x` will get coerced to `NaN` and make most arithmetic expressions return `NaN` (because `NaN` propagates). You can use this, for example, to test whether an argument to a function is arithmetically processable (usable "like" a number), and handle values that are not number-like by throwing an error, providing a default value, etc. This way, you can have a function that makes use of the full versatility JavaScript provides by implicitly converting values depending on context. diff --git a/documentation/versioned_docs/version-3.0.0/globals/location.mdx b/documentation/versioned_docs/version-3.0.0/globals/location.mdx deleted file mode 100644 index 1c549ffac4..0000000000 --- a/documentation/versioned_docs/version-3.0.0/globals/location.mdx +++ /dev/null @@ -1,18 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- - -# location - -The **`location`** read-only property returns a -[`Location`](../globals/WorkerLocation/WorkerLocation.mdx) object with information about the current location of the -document. - -See [`Location`](../globals/WorkerLocation/WorkerLocation.mdx) for all available properties. - -## Value - -A [`Location`](../globals/WorkerLocation/WorkerLocation.mdx) object. diff --git a/documentation/versioned_docs/version-3.0.0/globals/parseFloat.mdx b/documentation/versioned_docs/version-3.0.0/globals/parseFloat.mdx deleted file mode 100644 index 0cf52287e5..0000000000 --- a/documentation/versioned_docs/version-3.0.0/globals/parseFloat.mdx +++ /dev/null @@ -1,41 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# parseFloat() - -The **`parseFloat()`** function parses a string argument and returns a floating point number. - -## Syntax - -```js -parseFloat(string) -``` - -### Parameters - -- `string` - - : The value to parse, [coerced to a string](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String#string_coercion).

It is done as an initial step in the parsing after whitespace is removed. If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point. For example, although `1e3` technically encodes an integer (and will be correctly parsed to the integer `1000` by [`parseFloat()`](./parseFloat.mdx), `parseInt("1e3", 10)` returns `1`, because `e` is not a valid numeral in base 10.

Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

(The ECMA262 spec specifies a [simplified version of ISO 8601](https://tc39.es/ecma262/#sec-date-time-string-format), but other formats can be implementation-defined, which commonly include [IETF-compliant RFC 2822 timestamps](https://datatracker.ietf.org/doc/html/rfc2822#page-14).) - - > **Note:** When parsing date strings with the `Date` constructor (and `Date.parse`, they are equivalent), always make sure that the input conforms to the ISO 8601 format (`YYYY-MM-DDTHH:mm:ss.sssZ`) — the parsing behavior with other formats is implementation-defined and may not work across all browsers.

You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. - -If any parameter overflows its defined bounds, it "carries over". For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M. June 20th, 2020. - -Similarly, if any parameter underflows, it "borrows" from the higher positions. For example, `new Date(2020, 5, 0)` will return May 31st, 2020. - -- `year` - - : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year. See the [example](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date#interpretation_of_two-digit_years). -- `monthIndex` - - : Integer value representing the month, beginning with `0` for January to `11` for December. -- `day` _**optional**_ - - : Integer value representing the day of the month.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result.

The current property value will be replaced with the `replacer`'s return value for stringification.

Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value.

If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5.

If the `pattern` is a string, or if the corresponding capturing group isn't present in the regex, then the pattern will be replaced as a literal. If the group is present but isn't matched (because it's part of a disjunction), it will be replaced with an empty string. - -```js -"foo".replace(/(f)/, "$2"); -// "$2oo"; the regex doesn't have the second group - -"foo".replace("f", "$1"); -// "$1oo"; the pattern is a string, so it doesn't have any groups - -"foo".replace(/(f)|(g)/, "$2"); -// "oo"; the second group exists but isn't matched -``` - -### Specifying a function as the replacement - -You can specify a function as the second parameter. In this case, the function will be invoked after the match has been performed. The function's result (return value) will be used as the replacement string. - -> **Note:** The above-mentioned special replacement patterns do _not_ apply for strings returned from the replacer function. - -The function has the following signature: - -```js -function replacer(match, p1, p2, /* …, */ pN, offset, string, groups) { - return replacement; -} -``` - -The arguments to the function are as follows: - -- `match` - - : The matched substring. (Corresponds to `$&` above.) -- `p1, p2, …, pN` - - : The `n`th string found by a capture group (including named capturing groups), provided the first argument to `replace()` is a `RegExp` object. (Corresponds to `$1`, `$2`, etc. above.) For example, if the `pattern` is `/(\a+)(\b+)/`, then `p1` is the match for `\a+`, and `p2` is the match for `\b+`. If the group is part of a disjunction (e.g. `"abc".replace(/(a)|(b)/, replacer)`), the unmatched alternative will be `undefined`. -- `offset` - - : The offset of the matched substring within the whole string being examined. For example, if the whole string was `'abcd'`, and the matched substring was `'bc'`, then this argument will be `1`. -- `string` - - : The whole string being examined. -- `groups` - - : An object whose keys are the used group names, and whose values are the matched portions (`undefined` if not matched).

If `isNaN(x)` returns `true`, `x` will get coerced to `NaN` and make most arithmetic expressions return `NaN` (because `NaN` propagates).

You can replace `\xXX` with `%XX` and `\uXXXX` with `%uXXXX` to get a string that can be handled by `unescape()`. diff --git a/documentation/versioned_docs/version-3.1.0/index.mdx b/documentation/versioned_docs/version-3.1.0/index.mdx deleted file mode 100644 index 1670189828..0000000000 --- a/documentation/versioned_docs/version-3.1.0/index.mdx +++ /dev/null @@ -1,98 +0,0 @@ ---- -sidebar_position: 1 -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- - -import {Fiddle} from '@site/src/components/fiddle'; - -# JavaScript for Fastly Compute - -This site is the full SDK reference for [`@fastly/js-compute`](https://www.npmjs.com/package/%40fastly/js-compute), the module that provides the interface between your JavaScript code and the [Fastly Compute](https://www.fastly.com) platform. - -If you haven't used Fastly Compute before, start by [setting up your first Fastly Compute program](https://developer.fastly.com/learning/compute/) over on **developer.fastly.com** so that you have a working development environment. - -To learn more about the fundamentals of using JavaScript with Fastly Compute, see our [using JavaScript](https://developer.fastly.com/learning/compute/javascript/) guide. - -## Understanding the JavaScript SDK - -Incoming HTTP requests to [domains that are attached to your Fastly service](https://developer.fastly.com/learning/concepts/) will start an instance of your application and invoke a `fetch` event, which can be bound using the `addEventListener` function: - -```js -addEventListener("fetch", event => event.respondWith(handleRequest(event)) ); - -async function handleRequest(event) { - const req = event.request; - - return fetch(req, { - backend: "example_backend" - }); -} -``` - -Fastly specific features are available as named imports from `fastly:` prefixed modules, all of which are documented in this site.

(The ECMA262 spec specifies a [simplified version of ISO 8601](https://tc39.es/ecma262/#sec-date-time-string-format), but other formats can be implementation-defined, which commonly include [IETF-compliant RFC 2822 timestamps](https://datatracker.ietf.org/doc/html/rfc2822#page-14).) - - > **Note:** When parsing date strings with the `Date` constructor (and `Date.parse`, they are equivalent), always make sure that the input conforms to the ISO 8601 format (`YYYY-MM-DDTHH:mm:ss.sssZ`) — the parsing behavior with other formats is implementation-defined and may not work across all browsers.

You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. - -If any parameter overflows its defined bounds, it "carries over". For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M. June 20th, 2020. - -Similarly, if any parameter underflows, it "borrows" from the higher positions. For example, `new Date(2020, 5, 0)` will return May 31st, 2020. - -- `year` - - : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year. See the [example](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date#interpretation_of_two-digit_years). -- `monthIndex` - - : Integer value representing the month, beginning with `0` for January to `11` for December. -- `day` _**optional**_ - - : Integer value representing the day of the month. The default is `1`. -- `hours` _**optional**_ - - : Integer value between `0` and `23` representing the hour of the day.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result.

The current property value will be replaced with the `replacer`'s return value for stringification.

Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value.

If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5.

For example, `parseInt("42")` and `parseFloat("42")` would return the same value: a `Number` 42. - -## Description - -The `parseInt` function converts its first argument to a string, parses that string, then returns an integer or `NaN`. - -If not `NaN`, the return value will be the integer that is the first argument taken as a number in the specified `radix`. (For example, a `radix` of `10` converts from a decimal number, `8` converts from octal, `16` from hexadecimal, and so on.) - -The `radix` argument is converted to a number. If it's unprovided, or if the value becomes 0, `NaN` or `Infinity` (`undefined` is coerced to `NaN`), JavaScript assumes the following: - -1. If the input `string`, with leading whitespace and possible `+`/`-` signs removed, begins with `0x` or `0X` (a zero, followed by lowercase or uppercase X), `radix` is assumed to be `16` and the rest of the string is parsed as a hexadecimal number. -2. If the input `string` begins with any other value, the radix is `10` (decimal). - -> **Note:** Other prefixes like `0b`, which are valid in [number literals](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Lexical_grammar#binary), are treated as normal digits by `parseInt()`. `parseInt()` does _not_ treat strings beginning with a `0` character as octal values either. The only prefix that `parseInt()` recognizes is `0x` or `0X` for hexadecimal values — everything else is parsed as a decimal value if `radix` is missing. - -If the radix is `16`, `parseInt()` allows the string to be optionally prefixed by `0x` or `0X` after the optional sign character (`+`/`-`). - -If the radix value (coerced if necessary) is not in range \[2, 36] (inclusive) `parseInt` returns `NaN`. - -For radices above `10`, letters of the English alphabet indicate numerals greater than `9`. For example, for hexadecimal numbers (base `16`), `A` through `F` are used. The letters are case-insensitive. - -`parseInt` understands exactly two signs: `+` for positive, and `-` for negative. It is done as an initial step in the parsing after whitespace is removed. If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point. For example, although `1e3` technically encodes an integer (and will be correctly parsed to the integer `1000` by [`parseFloat()`](./parseFloat.mdx), `parseInt("1e3", 10)` returns `1`, because `e` is not a valid numeral in base 10. Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx). The [`BigInt`](./BigInt/BigInt.mdx) function supports parsing integers of arbitrary length accurately, by returning a `BigInt`. diff --git a/documentation/versioned_docs/version-3.2.0/globals/performance/now.mdx b/documentation/versioned_docs/version-3.2.0/globals/performance/now.mdx deleted file mode 100644 index da8f617cb9..0000000000 --- a/documentation/versioned_docs/version-3.2.0/globals/performance/now.mdx +++ /dev/null @@ -1,25 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- - -# performance.now() - -The **`performance.now()`** method returns a high resolution timestamp in milliseconds. -It represents the time elapsed since [`performance.timeOrigin`](./timeOrigin.mdx) (the time when the worker was instantiated). - -## Syntax - -```js -now() -``` - -### Parameters - -None. - -### Return value - -Returns a number which represents the time since worker instantation measured in milliseconds. diff --git a/documentation/versioned_docs/version-3.2.0/globals/performance/timeOrigin.mdx b/documentation/versioned_docs/version-3.2.0/globals/performance/timeOrigin.mdx deleted file mode 100644 index 772a527822..0000000000 --- a/documentation/versioned_docs/version-3.2.0/globals/performance/timeOrigin.mdx +++ /dev/null @@ -1,16 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- - -# performance.timeOrigin - -The **`timeOrigin`** read-only property of the Performance interface returns the high resolution timestamp that is used as the baseline for performance-related timestamps. - -This value represents the time when the worker was instantiated. - -### Value - -Returns a number which represents the time when the worker was instantation. \ No newline at end of file diff --git a/documentation/versioned_docs/version-3.2.0/globals/setInterval.mdx b/documentation/versioned_docs/version-3.2.0/globals/setInterval.mdx deleted file mode 100644 index 8133748deb..0000000000 --- a/documentation/versioned_docs/version-3.2.0/globals/setInterval.mdx +++ /dev/null @@ -1,61 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# setInterval() - -The **`setInterval()`** method, repeatedly -calls a function or executes a code snippet, with a fixed time delay between each -call. - -This method returns an interval ID which uniquely identifies the interval, so you -can remove it later by calling `clearInterval()`. - -## Syntax - -```js -setInterval(code) -setInterval(code, delay) - -setInterval(func) -setInterval(func, delay) -setInterval(func, delay, arg0) -setInterval(func, delay, arg0, arg1) -setInterval(func, delay, arg0, arg1, /* … ,*/ argN) -``` - -### Parameters - -- `func` - - : A `function` to be executed every `delay` milliseconds.

Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters.

For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M.

You, the programmer, write the `executor`.

Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled).

In summary: - -- If a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value is passed, the returned promise is already fulfilled with that value. -- If a thenable is passed, the returned promise will adopt the state of that thenable by calling the `then` method and passing a pair of resolving functions as arguments. (But because native promises directly pass through `Promise.resolve()` without creating a wrapper, the `then` method is not called on native promises.) If the resolver function receives another thenable object, it will be resolved agin, so that the eventual fulfillment value of the promise will never be thenable. diff --git a/documentation/versioned_docs/version-3.3.0/globals/Proxy/Proxy.mdx b/documentation/versioned_docs/version-3.3.0/globals/Proxy/Proxy.mdx deleted file mode 100644 index 2b96dd6a36..0000000000 --- a/documentation/versioned_docs/version-3.3.0/globals/Proxy/Proxy.mdx +++ /dev/null @@ -1,74 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Proxy() - -The **`Proxy()`** constructor is used to create `Proxy` objects. - -## Syntax - -```js -new Proxy(target, handler) -``` - -> **Note:** `Proxy()` can only be constructed with `new`.

For example, `parseInt("42")` and `parseFloat("42")` would return the same value: a `Number` 42. - -## Description - -The `parseInt` function converts its first argument to a string, parses that string, then returns an integer or `NaN`. - -If not `NaN`, the return value will be the integer that is the first argument taken as a number in the specified `radix`. (For example, a `radix` of `10` converts from a decimal number, `8` converts from octal, `16` from hexadecimal, and so on.) - -The `radix` argument is converted to a number. If it's unprovided, or if the value becomes 0, `NaN` or `Infinity` (`undefined` is coerced to `NaN`), JavaScript assumes the following: - -1. If the input `string`, with leading whitespace and possible `+`/`-` signs removed, begins with `0x` or `0X` (a zero, followed by lowercase or uppercase X), `radix` is assumed to be `16` and the rest of the string is parsed as a hexadecimal number. -2. If the input `string` begins with any other value, the radix is `10` (decimal). - -> **Note:** Other prefixes like `0b`, which are valid in [number literals](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Lexical_grammar#binary), are treated as normal digits by `parseInt()`. `parseInt()` does _not_ treat strings beginning with a `0` character as octal values either. The only prefix that `parseInt()` recognizes is `0x` or `0X` for hexadecimal values — everything else is parsed as a decimal value if `radix` is missing. - -If the radix is `16`, `parseInt()` allows the string to be optionally prefixed by `0x` or `0X` after the optional sign character (`+`/`-`). - -If the radix value (coerced if necessary) is not in range \[2, 36] (inclusive) `parseInt` returns `NaN`. - -For radices above `10`, letters of the English alphabet indicate numerals greater than `9`. For example, for hexadecimal numbers (base `16`), `A` through `F` are used. The letters are case-insensitive. - -`parseInt` understands exactly two signs: `+` for positive, and `-` for negative. It is done as an initial step in the parsing after whitespace is removed. If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point. For example, although `1e3` technically encodes an integer (and will be correctly parsed to the integer `1000` by [`parseFloat()`](./parseFloat.mdx), `parseInt("1e3", 10)` returns `1`, because `e` is not a valid numeral in base 10. Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters.

For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M.

You, the programmer, write the `executor`.

Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled).

In summary: - -- If a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value is passed, the returned promise is already fulfilled with that value. -- If a thenable is passed, the returned promise will adopt the state of that thenable by calling the `then` method and passing a pair of resolving functions as arguments. (But because native promises directly pass through `Promise.resolve()` without creating a wrapper, the `then` method is not called on native promises.) If the resolver function receives another thenable object, it will be resolved agin, so that the eventual fulfillment value of the promise will never be thenable. diff --git a/documentation/versioned_docs/version-3.3.2/globals/Proxy/Proxy.mdx b/documentation/versioned_docs/version-3.3.2/globals/Proxy/Proxy.mdx deleted file mode 100644 index 2b96dd6a36..0000000000 --- a/documentation/versioned_docs/version-3.3.2/globals/Proxy/Proxy.mdx +++ /dev/null @@ -1,74 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Proxy() - -The **`Proxy()`** constructor is used to create `Proxy` objects. - -## Syntax - -```js -new Proxy(target, handler) -``` - -> **Note:** `Proxy()` can only be constructed with `new`.

For example, `parseInt("42")` and `parseFloat("42")` would return the same value: a `Number` 42. - -## Description - -The `parseInt` function converts its first argument to a string, parses that string, then returns an integer or `NaN`. - -If not `NaN`, the return value will be the integer that is the first argument taken as a number in the specified `radix`. (For example, a `radix` of `10` converts from a decimal number, `8` converts from octal, `16` from hexadecimal, and so on.) - -The `radix` argument is converted to a number. If it's unprovided, or if the value becomes 0, `NaN` or `Infinity` (`undefined` is coerced to `NaN`), JavaScript assumes the following: - -1. If the input `string`, with leading whitespace and possible `+`/`-` signs removed, begins with `0x` or `0X` (a zero, followed by lowercase or uppercase X), `radix` is assumed to be `16` and the rest of the string is parsed as a hexadecimal number. -2. If the input `string` begins with any other value, the radix is `10` (decimal). - -> **Note:** Other prefixes like `0b`, which are valid in [number literals](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Lexical_grammar#binary), are treated as normal digits by `parseInt()`. `parseInt()` does _not_ treat strings beginning with a `0` character as octal values either. The only prefix that `parseInt()` recognizes is `0x` or `0X` for hexadecimal values — everything else is parsed as a decimal value if `radix` is missing. - -If the radix is `16`, `parseInt()` allows the string to be optionally prefixed by `0x` or `0X` after the optional sign character (`+`/`-`). - -If the radix value (coerced if necessary) is not in range \[2, 36] (inclusive) `parseInt` returns `NaN`. - -For radices above `10`, letters of the English alphabet indicate numerals greater than `9`. For example, for hexadecimal numbers (base `16`), `A` through `F` are used. The letters are case-insensitive. - -`parseInt` understands exactly two signs: `+` for positive, and `-` for negative. It is done as an initial step in the parsing after whitespace is removed. If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point. For example, although `1e3` technically encodes an integer (and will be correctly parsed to the integer `1000` by [`parseFloat()`](./parseFloat.mdx), `parseInt("1e3", 10)` returns `1`, because `e` is not a valid numeral in base 10. Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters.

For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M.

You, the programmer, write the `executor`.

Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled).

In summary: - -- If a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value is passed, the returned promise is already fulfilled with that value. -- If a thenable is passed, the returned promise will adopt the state of that thenable by calling the `then` method and passing a pair of resolving functions as arguments. (But because native promises directly pass through `Promise.resolve()` without creating a wrapper, the `then` method is not called on native promises.) If the resolver function receives another thenable object, it will be resolved agin, so that the eventual fulfillment value of the promise will never be thenable. diff --git a/documentation/versioned_docs/version-3.4.0/globals/Proxy/Proxy.mdx b/documentation/versioned_docs/version-3.4.0/globals/Proxy/Proxy.mdx deleted file mode 100644 index 2b96dd6a36..0000000000 --- a/documentation/versioned_docs/version-3.4.0/globals/Proxy/Proxy.mdx +++ /dev/null @@ -1,74 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Proxy() - -The **`Proxy()`** constructor is used to create `Proxy` objects. - -## Syntax - -```js -new Proxy(target, handler) -``` - -> **Note:** `Proxy()` can only be constructed with `new`.

If `isNaN(x)` returns `true`, `x` will get coerced to `NaN` and make most arithmetic expressions return `NaN` (because `NaN` propagates).

(The ECMA262 spec specifies a [simplified version of ISO 8601](https://tc39.es/ecma262/#sec-date-time-string-format), but other formats can be implementation-defined, which commonly include [IETF-compliant RFC 2822 timestamps](https://datatracker.ietf.org/doc/html/rfc2822#page-14).) - - > **Note:** When parsing date strings with the `Date` constructor (and `Date.parse`, they are equivalent), always make sure that the input conforms to the ISO 8601 format (`YYYY-MM-DDTHH:mm:ss.sssZ`) — the parsing behavior with other formats is implementation-defined and may not work across all browsers.

You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. - -If any parameter overflows its defined bounds, it "carries over". For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M. June 20th, 2020. - -Similarly, if any parameter underflows, it "borrows" from the higher positions. For example, `new Date(2020, 5, 0)` will return May 31st, 2020. - -- `year` - - : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year. See the [example](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date#interpretation_of_two-digit_years). -- `monthIndex` - - : Integer value representing the month, beginning with `0` for January to `11` for December. -- `day` _**optional**_ - - : Integer value representing the day of the month.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result.

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously).

For example, `parseInt("42")` and `parseFloat("42")` would return the same value: a `Number` 42. - -## Description - -The `parseInt` function converts its first argument to a string, parses that string, then returns an integer or `NaN`. - -If not `NaN`, the return value will be the integer that is the first argument taken as a number in the specified `radix`. (For example, a `radix` of `10` converts from a decimal number, `8` converts from octal, `16` from hexadecimal, and so on.) - -The `radix` argument is converted to a number. If it's unprovided, or if the value becomes 0, `NaN` or `Infinity` (`undefined` is coerced to `NaN`), JavaScript assumes the following: - -1. If the input `string`, with leading whitespace and possible `+`/`-` signs removed, begins with `0x` or `0X` (a zero, followed by lowercase or uppercase X), `radix` is assumed to be `16` and the rest of the string is parsed as a hexadecimal number. -2. If the input `string` begins with any other value, the radix is `10` (decimal). - -> **Note:** Other prefixes like `0b`, which are valid in [number literals](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Lexical_grammar#binary), are treated as normal digits by `parseInt()`. `parseInt()` does _not_ treat strings beginning with a `0` character as octal values either. The only prefix that `parseInt()` recognizes is `0x` or `0X` for hexadecimal values — everything else is parsed as a decimal value if `radix` is missing. - -If the radix is `16`, `parseInt()` allows the string to be optionally prefixed by `0x` or `0X` after the optional sign character (`+`/`-`). - -If the radix value (coerced if necessary) is not in range \[2, 36] (inclusive) `parseInt` returns `NaN`. - -For radices above `10`, letters of the English alphabet indicate numerals greater than `9`. For example, for hexadecimal numbers (base `16`), `A` through `F` are used. The letters are case-insensitive. - -`parseInt` understands exactly two signs: `+` for positive, and `-` for negative. It is done as an initial step in the parsing after whitespace is removed. If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point. For example, although `1e3` technically encodes an integer (and will be correctly parsed to the integer `1000` by [`parseFloat()`](./parseFloat.mdx), `parseInt("1e3", 10)` returns `1`, because `e` is not a valid numeral in base 10. Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component).

For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M.

Each must be a string that corresponds to a valid JavaScript parameter (any of plain [identifier](https://developer.mozilla.org/docs/Glossary/Identifier), [rest parameter](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/rest_parameters), or [destructured](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment) parameter, optionally with a [default](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/Default_parameters)), or a list of such strings separated with commas. - - As the parameters are parsed in the same way as function expressions, whitespace and comments are accepted. For example: `"x", "theValue = 42", "[a, b] /* numbers */"` — or `"x, theValue = 42, [a, b] /* numbers */"`. (`"x, theValue = 42", "[a, b]"` is also correct, though very confusing to read.) - -- `functionBody` - - : A string containing the JavaScript statements comprising the function definition. - -## Description - -`Function` objects created with the `Function` constructor are parsed when the function is created. This is less efficient than creating a function with a [function expression](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/function) or [function declaration](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/function) and calling it within your code, because such functions are parsed with the rest of the code. - -All arguments passed to the function, except the last, are treated as the names of the identifiers of the parameters in the function to be created, in the order in which they are passed. The function will be dynamically compiled as a function expression, with the source assembled in the following fashion: - -```js -`function anonymous(${args.join(",")} -) { -${functionBody} -}` -``` - -This is observable by calling the function's [`toString()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Function/toString) method. - -However, unlike normal [function expressions](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/function), the name `anonymous` is not added to the `functionBody`'s scope, since `functionBody` only has access the global scope. If `functionBody` is not in [strict mode](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Strict_mode) (the body itself needs to have the `"use strict"` directive since it doesn't inherit the strictness from the context), you may use [`arguments.callee`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/arguments/callee) to refer to the function itself. Alternatively, you can define the recursive part as an inner function: - -```js -const recursiveFn = new Function("count", ` -(function recursiveFn(count) { - if (count < 0) { - return; - } - console.log(count); - recursiveFn(count - 1); -})(count); -`); -``` - -Note that the two dynamic parts of the assembled source — the parameters list `args.join(",")` and `functionBody` — will first be parsed separately to ensure they are each syntactically valid. This prevents injection-like attempts. - -```js -new Function("/*", "*/) {"); -// SyntaxError: Unexpected end of arg string -// Doesn't become "function anonymous(/*) {*/) {}" -``` diff --git a/documentation/versioned_docs/version-3.6.0/globals/Function/prototype/apply.mdx b/documentation/versioned_docs/version-3.6.0/globals/Function/prototype/apply.mdx deleted file mode 100644 index 7684098326..0000000000 --- a/documentation/versioned_docs/version-3.6.0/globals/Function/prototype/apply.mdx +++ /dev/null @@ -1,37 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Function.prototype.apply() - -The **`apply()`** method calls the specified function with a given `this` value, and `arguments` provided as an array (or an [array-like object](https://developer.mozilla.org/docs/Web/JavaScript/Guide/Indexed_collections#working_with_array-like_objects)). - - - -## Syntax - -```js -apply(thisArg) -apply(thisArg, argsArray) -``` - -### Parameters - -- `thisArg` - - : The value of `this` provided for the call to `func`.

You, the programmer, write the `executor`.

Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled).

In summary: - -- If a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value is passed, the returned promise is already fulfilled with that value. -- If a thenable is passed, the returned promise will adopt the state of that thenable by calling the `then` method and passing a pair of resolving functions as arguments. (But because native promises directly pass through `Promise.resolve()` without creating a wrapper, the `then` method is not called on native promises.) If the resolver function receives another thenable object, it will be resolved agin, so that the eventual fulfillment value of the promise will never be thenable. diff --git a/documentation/versioned_docs/version-3.6.0/globals/Proxy/Proxy.mdx b/documentation/versioned_docs/version-3.6.0/globals/Proxy/Proxy.mdx deleted file mode 100644 index 2b96dd6a36..0000000000 --- a/documentation/versioned_docs/version-3.6.0/globals/Proxy/Proxy.mdx +++ /dev/null @@ -1,74 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Proxy() - -The **`Proxy()`** constructor is used to create `Proxy` objects. - -## Syntax - -```js -new Proxy(target, handler) -``` - -> **Note:** `Proxy()` can only be constructed with `new`.

For example, `parseInt("42")` and `parseFloat("42")` would return the same value: a `Number` 42. - -## Description - -The `parseInt` function converts its first argument to a string, parses that string, then returns an integer or `NaN`. - -If not `NaN`, the return value will be the integer that is the first argument taken as a number in the specified `radix`. (For example, a `radix` of `10` converts from a decimal number, `8` converts from octal, `16` from hexadecimal, and so on.) - -The `radix` argument is converted to a number. If it's unprovided, or if the value becomes 0, `NaN` or `Infinity` (`undefined` is coerced to `NaN`), JavaScript assumes the following: - -1. If the input `string`, with leading whitespace and possible `+`/`-` signs removed, begins with `0x` or `0X` (a zero, followed by lowercase or uppercase X), `radix` is assumed to be `16` and the rest of the string is parsed as a hexadecimal number. -2. If the input `string` begins with any other value, the radix is `10` (decimal). - -> **Note:** Other prefixes like `0b`, which are valid in [number literals](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Lexical_grammar#binary), are treated as normal digits by `parseInt()`. `parseInt()` does _not_ treat strings beginning with a `0` character as octal values either. The only prefix that `parseInt()` recognizes is `0x` or `0X` for hexadecimal values — everything else is parsed as a decimal value if `radix` is missing. - -If the radix is `16`, `parseInt()` allows the string to be optionally prefixed by `0x` or `0X` after the optional sign character (`+`/`-`). - -If the radix value (coerced if necessary) is not in range \[2, 36] (inclusive) `parseInt` returns `NaN`. - -For radices above `10`, letters of the English alphabet indicate numerals greater than `9`. For example, for hexadecimal numbers (base `16`), `A` through `F` are used. The letters are case-insensitive. - -`parseInt` understands exactly two signs: `+` for positive, and `-` for negative. It is done as an initial step in the parsing after whitespace is removed. If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point. For example, although `1e3` technically encodes an integer (and will be correctly parsed to the integer `1000` by [`parseFloat()`](./parseFloat.mdx), `parseInt("1e3", 10)` returns `1`, because `e` is not a valid numeral in base 10. Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. - -If any parameter overflows its defined bounds, it "carries over". For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M. June 20th, 2020. - -Similarly, if any parameter underflows, it "borrows" from the higher positions. For example, `new Date(2020, 5, 0)` will return May 31st, 2020. - -- `year` - - : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year. See the [example](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date#interpretation_of_two-digit_years). -- `monthIndex` - - : Integer value representing the month, beginning with `0` for January to `11` for December. -- `day` _**optional**_ - - : Integer value representing the day of the month.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result.

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously).

For example, `parseInt("42")` and `parseFloat("42")` would return the same value: a `Number` 42. - -## Description - -The `parseInt` function converts its first argument to a string, parses that string, then returns an integer or `NaN`. - -If not `NaN`, the return value will be the integer that is the first argument taken as a number in the specified `radix`. (For example, a `radix` of `10` converts from a decimal number, `8` converts from octal, `16` from hexadecimal, and so on.) - -The `radix` argument is converted to a number. If it's unprovided, or if the value becomes 0, `NaN` or `Infinity` (`undefined` is coerced to `NaN`), JavaScript assumes the following: - -1. If the input `string`, with leading whitespace and possible `+`/`-` signs removed, begins with `0x` or `0X` (a zero, followed by lowercase or uppercase X), `radix` is assumed to be `16` and the rest of the string is parsed as a hexadecimal number. -2. If the input `string` begins with any other value, the radix is `10` (decimal). - -> **Note:** Other prefixes like `0b`, which are valid in [number literals](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Lexical_grammar#binary), are treated as normal digits by `parseInt()`. `parseInt()` does _not_ treat strings beginning with a `0` character as octal values either. The only prefix that `parseInt()` recognizes is `0x` or `0X` for hexadecimal values — everything else is parsed as a decimal value if `radix` is missing. - -If the radix is `16`, `parseInt()` allows the string to be optionally prefixed by `0x` or `0X` after the optional sign character (`+`/`-`). - -If the radix value (coerced if necessary) is not in range \[2, 36] (inclusive) `parseInt` returns `NaN`. - -For radices above `10`, letters of the English alphabet indicate numerals greater than `9`. For example, for hexadecimal numbers (base `16`), `A` through `F` are used. The letters are case-insensitive. - -`parseInt` understands exactly two signs: `+` for positive, and `-` for negative. It is done as an initial step in the parsing after whitespace is removed. If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point. For example, although `1e3` technically encodes an integer (and will be correctly parsed to the integer `1000` by [`parseFloat()`](./parseFloat.mdx), `parseInt("1e3", 10)` returns `1`, because `e` is not a valid numeral in base 10. Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

When the time zone offset is absent, -date-only forms are interpreted as a UTC time and date-time forms are interpreted as -local time. - -While time zone specifiers are used during date string parsing to interpret the -argument, the value returned is always the number of milliseconds between January 1, -1970 00:00:00 UTC and the point in time represented by the argument or `NaN`. - -Because `parse()` is a static method of `Date`, it is called as -`Date.parse()` rather than as a method of a `Date` instance. - -### Fall-back to implementation-specific date formats - -> **Note:** This section contains implementation-specific behavior that can be inconsistent -> across implementations. - -The ECMAScript specification states: If the String does not conform to the standard -format the function may fall back to any implementation–specific heuristics or -implementation–specific parsing algorithm. Unrecognizable strings or dates containing -illegal element values in ISO formatted strings shall cause `Date.parse()` to -return [`NaN`](../NaN.mdx). - -However, invalid values in date strings not recognized as simplified ISO format as -defined by ECMA-262 may or may not result in [`NaN`](../NaN.mdx), depending on the browser -and values provided, e.g.: - -```js -// Non-ISO string with invalid date values -new Date("23/25/2014"); -``` - -will be treated as a local date of 25 November, 2015 in Firefox 30 and an invalid date -in Safari 7. - -However, if the string is recognized as an ISO format string and it contains invalid -values, it will return [`NaN`](../NaN.mdx): - -```js -// ISO string with invalid values -new Date("2014-25-23").toISOString(); -// throws "RangeError: invalid date" -``` - -SpiderMonkey's implementation-specific heuristic can be found in [`jsdate.cpp`](https://searchfox.org/mozilla-central/source/js/src/jsdate.cpp?rev=64553c483cd1#889). -The string `"10 06 2014"` is an example of a non-conforming ISO format and -thus falls back to a custom routine.

Therefore `Date` objects produced using those strings may represent different moments in time depending on the version of ECMAScript supported unless the system is set with a local time zone of UTC. This means that two date strings that appear equivalent may result in two different values depending on the format of the string that is being converted. diff --git a/documentation/versioned_docs/version-3.8.0/globals/Date/prototype/@@toPrimitive.mdx b/documentation/versioned_docs/version-3.8.0/globals/Date/prototype/@@toPrimitive.mdx deleted file mode 100644 index 0c9c5443f1..0000000000 --- a/documentation/versioned_docs/version-3.8.0/globals/Date/prototype/@@toPrimitive.mdx +++ /dev/null @@ -1,40 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Date.prototype\[Symbol.toPrimitive] - -The **`[Symbol.toPrimitive]()`** method converts a `Date` -object to a primitive value. - -## Syntax - -```js -Date()[Symbol.toPrimitive](hint) -``` - -### Return value - -The primitive value of the given `Date` object.

Each must be a string that corresponds to a valid JavaScript parameter (any of plain [identifier](https://developer.mozilla.org/docs/Glossary/Identifier), [rest parameter](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/rest_parameters), or [destructured](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment) parameter, optionally with a [default](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/Default_parameters)), or a list of such strings separated with commas. - - As the parameters are parsed in the same way as function expressions, whitespace and comments are accepted. For example: `"x", "theValue = 42", "[a, b] /* numbers */"` — or `"x, theValue = 42, [a, b] /* numbers */"`. (`"x, theValue = 42", "[a, b]"` is also correct, though very confusing to read.) - -- `functionBody` - - : A string containing the JavaScript statements comprising the function definition. - -## Description - -`Function` objects created with the `Function` constructor are parsed when the function is created. This is less efficient than creating a function with a [function expression](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/function) or [function declaration](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/function) and calling it within your code, because such functions are parsed with the rest of the code. - -All arguments passed to the function, except the last, are treated as the names of the identifiers of the parameters in the function to be created, in the order in which they are passed. The function will be dynamically compiled as a function expression, with the source assembled in the following fashion: - -```js -`function anonymous(${args.join(",")} -) { -${functionBody} -}` -``` - -This is observable by calling the function's [`toString()`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Function/toString) method. - -However, unlike normal [function expressions](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Operators/function), the name `anonymous` is not added to the `functionBody`'s scope, since `functionBody` only has access the global scope. If `functionBody` is not in [strict mode](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Strict_mode) (the body itself needs to have the `"use strict"` directive since it doesn't inherit the strictness from the context), you may use [`arguments.callee`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Functions/arguments/callee) to refer to the function itself. Alternatively, you can define the recursive part as an inner function: - -```js -const recursiveFn = new Function("count", ` -(function recursiveFn(count) { - if (count < 0) { - return; - } - console.log(count); - recursiveFn(count - 1); -})(count); -`); -``` - -Note that the two dynamic parts of the assembled source — the parameters list `args.join(",")` and `functionBody` — will first be parsed separately to ensure they are each syntactically valid. This prevents injection-like attempts. - -```js -new Function("/*", "*/) {"); -// SyntaxError: Unexpected end of arg string -// Doesn't become "function anonymous(/*) {*/) {}" -``` diff --git a/documentation/versioned_docs/version-3.8.0/globals/Function/prototype/apply.mdx b/documentation/versioned_docs/version-3.8.0/globals/Function/prototype/apply.mdx deleted file mode 100644 index 7684098326..0000000000 --- a/documentation/versioned_docs/version-3.8.0/globals/Function/prototype/apply.mdx +++ /dev/null @@ -1,37 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Function.prototype.apply() - -The **`apply()`** method calls the specified function with a given `this` value, and `arguments` provided as an array (or an [array-like object](https://developer.mozilla.org/docs/Web/JavaScript/Guide/Indexed_collections#working_with_array-like_objects)). - - - -## Syntax - -```js -apply(thisArg) -apply(thisArg, argsArray) -``` - -### Parameters - -- `thisArg` - - : The value of `this` provided for the call to `func`.

(Returning a BigInt will throw as well.) -- If you return a `Function`, `Symbol`, or [`undefined`](../../globals/undefined.mdx), the property is not included in the output. -- If you return any other object, the object is recursively stringified, calling the `replacer` function on each property. - -> **Note:** When parsing JSON generated with `replacer` functions, you would likely want to use the [`reviver`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#using_the_reviver_parameter) parameter to perform the reverse operation. - -Typically, array elements' index would never shift (even when the element is an invalid value like a function, it will become `null` instead of omitted).

You, the programmer, write the `executor`.

Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled).

In summary: - -- If a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value is passed, the returned promise is already fulfilled with that value. -- If a thenable is passed, the returned promise will adopt the state of that thenable by calling the `then` method and passing a pair of resolving functions as arguments. (But because native promises directly pass through `Promise.resolve()` without creating a wrapper, the `then` method is not called on native promises.) If the resolver function receives another thenable object, it will be resolved agin, so that the eventual fulfillment value of the promise will never be thenable. diff --git a/documentation/versioned_docs/version-3.8.0/globals/Proxy/Proxy.mdx b/documentation/versioned_docs/version-3.8.0/globals/Proxy/Proxy.mdx deleted file mode 100644 index 2b96dd6a36..0000000000 --- a/documentation/versioned_docs/version-3.8.0/globals/Proxy/Proxy.mdx +++ /dev/null @@ -1,74 +0,0 @@ ---- -hide_title: false -hide_table_of_contents: false -pagination_next: null -pagination_prev: null ---- -# Proxy() - -The **`Proxy()`** constructor is used to create `Proxy` objects. - -## Syntax - -```js -new Proxy(target, handler) -``` - -> **Note:** `Proxy()` can only be constructed with `new`.

For example, `parseInt("42")` and `parseFloat("42")` would return the same value: a `Number` 42. - -## Description - -The `parseInt` function converts its first argument to a string, parses that string, then returns an integer or `NaN`. - -If not `NaN`, the return value will be the integer that is the first argument taken as a number in the specified `radix`. (For example, a `radix` of `10` converts from a decimal number, `8` converts from octal, `16` from hexadecimal, and so on.) - -The `radix` argument is converted to a number. If it's unprovided, or if the value becomes 0, `NaN` or `Infinity` (`undefined` is coerced to `NaN`), JavaScript assumes the following: - -1. If the input `string`, with leading whitespace and possible `+`/`-` signs removed, begins with `0x` or `0X` (a zero, followed by lowercase or uppercase X), `radix` is assumed to be `16` and the rest of the string is parsed as a hexadecimal number. -2. If the input `string` begins with any other value, the radix is `10` (decimal). - -> **Note:** Other prefixes like `0b`, which are valid in [number literals](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Lexical_grammar#binary), are treated as normal digits by `parseInt()`. `parseInt()` does _not_ treat strings beginning with a `0` character as octal values either. The only prefix that `parseInt()` recognizes is `0x` or `0X` for hexadecimal values — everything else is parsed as a decimal value if `radix` is missing. - -If the radix is `16`, `parseInt()` allows the string to be optionally prefixed by `0x` or `0X` after the optional sign character (`+`/`-`). - -If the radix value (coerced if necessary) is not in range \[2, 36] (inclusive) `parseInt` returns `NaN`. - -For radices above `10`, letters of the English alphabet indicate numerals greater than `9`. For example, for hexadecimal numbers (base `16`), `A` through `F` are used. The letters are case-insensitive. - -`parseInt` understands exactly two signs: `+` for positive, and `-` for negative. It is done as an initial step in the parsing after whitespace is removed. If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point. For example, although `1e3` technically encodes an integer (and will be correctly parsed to the integer `1000` by [`parseFloat()`](./parseFloat.mdx), `parseInt("1e3", 10)` returns `1`, because `e` is not a valid numeral in base 10. Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).

(The ECMA262 spec specifies a [simplified version of ISO 8601](https://tc39.es/ecma262/#sec-date-time-string-format), but other formats can be implementation-defined, which commonly include [IETF-compliant RFC 2822 timestamps](https://datatracker.ietf.org/doc/html/rfc2822#page-14).) - - > **Note:** When parsing date strings with the `Date` constructor (and `Date.parse`, they are equivalent), always make sure that the input conforms to the ISO 8601 format (`YYYY-MM-DDTHH:mm:ss.sssZ`) — the parsing behavior with other formats is implementation-defined and may not work across all browsers.

You are therefore also advised to make sure the input format is consistent between the two types. - -#### Date object - -- `dateObject` - - : An existing `Date` object. This effectively makes a copy of the existing `Date` object with the same date and time. This is equivalent to `new Date(dateObject.valueOf())`, except the `valueOf()` method is not called. - -When one parameter is passed to the `Date()` constructor, `Date` instances are specially treated. All other values are [converted to primitives](https://developer.mozilla.org/docs/Web/JavaScript/Data_structures#primitive_coercion). If the result is a string, it will be parsed as a date string. Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. - -#### Individual date and time component values - -Given at least a year and month, this form of `Date()` returns a `Date` object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Any missing fields are given the lowest possible value (`1` for `day` and `0` for every other component). The parameter values are all evaluated against the local time zone, rather than UTC. - -If any parameter overflows its defined bounds, it "carries over". For example, if a `monthIndex` greater than `11` is passed in, those months will cause the year to increment; if a `minutes` greater than `59` is passed in, `hours` will increment accordingly, etc. Therefore, `new Date(1990, 12, 1)` will return January 1st, 1991; `new Date(2020, 5, 19, 25, 65)` will return 2:05 A.M. June 20th, 2020. - -Similarly, if any parameter underflows, it "borrows" from the higher positions. For example, `new Date(2020, 5, 0)` will return May 31st, 2020. - -- `year` - - : Integer value representing the year. Values from `0` to `99` map to the years `1900` to `1999`. All other values are the actual year. See the [example](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Date#interpretation_of_two-digit_years). -- `monthIndex` - - : Integer value representing the month, beginning with `0` for January to `11` for December. -- `day` _**optional**_ - - : Integer value representing the day of the month.

However, if the BigInt has a `toJSON()` method (through monkeypatching: `BigInt.prototype.toJSON = ...`), that method can provide the serialization result.

You, the programmer, write the `executor`. Its signature is expected to be: - -```js -function executor(resolveFunc, rejectFunc) { - // Typically, some asynchronous operation that accepts a callback, - // like the `readFile` function above -} -``` - -`resolveFunc` and `rejectFunc` are also functions, and you can give them whatever actual names you want. Their signatures are simple: they accept a single parameter of any type. - -```js -resolveFunc(value); // call on resolved -rejectFunc(reason); // call on rejected -``` - -The `value` parameter passed to `resolveFunc` can be another promise object, in which case the newly constructed promise's state will be "locked in" to the promise passed (as part of the [resolution](#resolver_function) promise). The `rejectFunc` has semantics close to the [`throw`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/throw) statement, so `reason` is typically an [`Error`](../../globals/Error/Error.mdx) instance. If either `value` or `reason` is omitted, the promise is fulfilled/rejected with `undefined`. - -The `executor`'s completion state has limited effect on the promise's state: - -- The `executor` return value is ignored. `return` statements within the `executor` merely impact control flow and alter whether a part of the function is executed, but do not have any impact on the promise's fulfillment value. If `executor` exits and it's impossible for `resolveFunc` or `rejectFunc` to be called in the future (for example, there are no async tasks scheduled), then the promise remains pending forever. -- If an error is thrown in the `executor`, the promise is rejected, unless `resolveFunc` or `rejectFunc` has already been called. - -> **Note:** The existence of pending promises does not prevent the program from exiting. If the event loop is empty, the program exits despite any pending promises (because those are necessarily forever-pending). - -Here's a summary of the typical flow: - -1. At the time when the constructor generates the new `Promise` object, it also generates a corresponding pair of functions for `resolveFunc` and `rejectFunc`; these are "tethered" to the `Promise` object. -2. `executor` typically wraps some asynchronous operation which provides a callback-based API. The callback (the one passed to the original callback-based API) is defined within the `executor` code, so it has access to the `resolveFunc` and `rejectFunc`. -3. The `executor` is called synchronously (as soon as the `Promise` is constructed) with the `resolveFunc` and `rejectFunc` functions as arguments. -4. The code within the `executor` has the opportunity to perform some operation. The eventual completion of the asynchronous task is communicated with the promise instance via the side effect caused by `resolveFunc` or `rejectFunc`. The side effect is that the `Promise` object becomes "resolved". - - If `resolveFunc` is called first, the value passed will be [resolved](#resolver_function). The promise may stay pending (in case another [thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) is passed), become fulfilled (in most cases where a non-thenable value is passed), or become rejected (in case of an invalid resolution value). - - If `rejectFunc` is called first, the promise instantly becomes rejected. - - Once one of the resolving functions (`resolveFunc` or `rejectFunc`) is called, the promise stays resolved. Only the first call to `resolveFunc` or `rejectFunc` affects the promise's eventual state, and subsequent calls to either function can neither change the fulfillment value/rejection reason nor toggle its eventual state from "fulfilled" to "rejected" or opposite. - - If `executor` exits by throwing an error, then the promise is rejected. However, the error is ignored if one of the resolving functions has already been called (so that the promise is already resolved). - - Resolving the promise does not necessarily cause the promise to become fulfilled or rejected (i.e. settled). The promise may still be pending because it's resolved with another thenable, but its eventual state will match that of the resolved thenable. -5. Once the promise settles, it (asynchronously) invokes any further handlers associated through [`Promise.prototype.then`](../../globals/Promise/prototype/then.mdx), [`Promise.prototype.catch`](../../globals/Promise/prototype/catch.mdx), or [`Promise.prototype.finally`](../../globals/Promise/prototype/finally.mdx). The eventual fulfillment value or rejection reason is passed to the invocation of fulfillment and rejection handlers as an input parameter (see [Chained Promises](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#chained_promises)). - -For example, the callback-based `readFile` API above can be transformed into a promise-based one. - -```js -const readFilePromise = (path) => - new Promise((resolve, reject) => { - readFile(path, (error, result) => { - if (error) { - reject(error); - } else { - resolve(result); - } - }); - }); - -readFilePromise("./data.txt") - .then((result) => console.log(result)) - .catch((error) => console.error("Failed to read data")); -``` - -### Resolver function - -The resolver function `resolveFunc` has the following behaviors: - -- If it's called with the same value as the newly created promise (the promise it's "tethered to"), the promise is rejected with a [`TypeError`](../../globals/TypeError/TypeError.mdx). -- If it's called with a non-[thenable](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#thenables) value (a primitive, or an object whose `then` property is not callable, including when the property is not present), the promise is immediately fulfilled with that value. -- If it's called with a thenable value (including another `Promise` instance), then the thenable's `then` method is saved and called in the future (it's always called asynchronously).

For example, `parseInt("42")` and `parseFloat("42")` would return the same value: a `Number` 42. - -## Description - -The `parseInt` function converts its first argument to a string, parses that string, then returns an integer or `NaN`. - -If not `NaN`, the return value will be the integer that is the first argument taken as a number in the specified `radix`. (For example, a `radix` of `10` converts from a decimal number, `8` converts from octal, `16` from hexadecimal, and so on.) - -The `radix` argument is converted to a number. If it's unprovided, or if the value becomes 0, `NaN` or `Infinity` (`undefined` is coerced to `NaN`), JavaScript assumes the following: - -1. If the input `string`, with leading whitespace and possible `+`/`-` signs removed, begins with `0x` or `0X` (a zero, followed by lowercase or uppercase X), `radix` is assumed to be `16` and the rest of the string is parsed as a hexadecimal number. -2. If the input `string` begins with any other value, the radix is `10` (decimal). - -> **Note:** Other prefixes like `0b`, which are valid in [number literals](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Lexical_grammar#binary), are treated as normal digits by `parseInt()`. `parseInt()` does _not_ treat strings beginning with a `0` character as octal values either. The only prefix that `parseInt()` recognizes is `0x` or `0X` for hexadecimal values — everything else is parsed as a decimal value if `radix` is missing. - -If the radix is `16`, `parseInt()` allows the string to be optionally prefixed by `0x` or `0X` after the optional sign character (`+`/`-`). - -If the radix value (coerced if necessary) is not in range \[2, 36] (inclusive) `parseInt` returns `NaN`. - -For radices above `10`, letters of the English alphabet indicate numerals greater than `9`. For example, for hexadecimal numbers (base `16`), `A` through `F` are used. The letters are case-insensitive. - -`parseInt` understands exactly two signs: `+` for positive, and `-` for negative. It is done as an initial step in the parsing after whitespace is removed. If no signs are found, the algorithm moves to the following step; otherwise, it removes the sign and runs the number-parsing on the rest of the string. - -If `parseInt` encounters a character that is not a numeral in the specified `radix`, it ignores it and all succeeding characters and returns the integer value parsed up to that point. For example, although `1e3` technically encodes an integer (and will be correctly parsed to the integer `1000` by [`parseFloat()`](./parseFloat.mdx), `parseInt("1e3", 10)` returns `1`, because `e` is not a valid numeral in base 10. Because `.` is not a numeral either, the return value will always be an integer. - -If the first character cannot be converted to a number with the radix in use, `parseInt` returns `NaN`. Leading whitespace is allowed. - -For arithmetic purposes, the `NaN` value is not a number in any radix. You can call the [`Number.isNaN`](./Number/isNaN.mdx) function to determine if the result of `parseInt` is `NaN`. If `NaN` is passed on to arithmetic operations, the operation result will also be `NaN`. - -Because large numbers use the `e` character in their string representation (e.g. `6.022e23` for 6.022 × 1023), using `parseInt` to truncate numbers will produce unexpected results when used on very large or very small numbers. `parseInt` should _not_ be used as a substitute for [`Math.trunc()`](./Math/trunc.mdx). - -To convert a number to its string literal in a particular radix, use [`thatNumber.toString(radix)`](./Number/prototype/toString.mdx). - -Because `parseInt()` returns a number, it may suffer from loss of precision if the integer represented by the string is [outside the safe range](./Number/isSafeInteger.mdx).
