A mini clone of the Lodash library.
BEWARE: This library was published for learning purposes. It is not intended for use in production-grade software.
This project was created and published by me as part of my learnings at Lighthouse Labs.
Install it:
npm install @lanzyy/lotide
Require it:
const _ = require('@lanzyy/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
-
assertEqual: Assertion that two values (primitives) are equal. -
head: A commonly used function for arrays is to retrieve the first element from the array. -
tail: Return the "tail" of an array, everything except for the first item (head). -
eqArrays: Compares Arrays for a perfect match. -
assertArrayEquals: Assertion that two arrays are equal. -
without: Removes an item in an array. -
flatten: flattens multi-dimensional arrays. -
middle: Return an array with only the middle element(s) of the provided array. -
countOnly: Take in a collection of items and return counts for a specific subset of those items. -
countLetters: Take in a sentence (as a string) and then return a count of each of the letters in that sentence. -
letterPositions: Return all the indices (zero-based positions) in the string where each character is found. -
findKeyByValue: Help us search for a key on an object where its value matches a given value. -
eqObjects: Compares objects for a perfect match. -
assertObjectsEqual: Assertion that two objects are equal. -
map: This function will take in two arguments: An array to map and a callback function. It will return a new array based on the results of the callback function. -
takeUntil: It will take in two parameters as well: The array to work with and the callback (which Lodash calls "predicate"). The function will return a slice of the array with elements taken from the beginning. -
findKey: Takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value.
