Provides just basic utilities (and shims) which help setup basic configurations in ES3 engines.
See es5-ext project for extensive list of ECMAScript 5 based extensions
$ npm install es3-ext
To port it to Browser or any other (non CJS) environment, use your favorite CJS bundler. No favorite yet? Try: Browserify, Webmake or Webpack
You can force ES5 features to be implemented in your environment, e.g. following will assign bind
function to Function.prototype
(only if it's not implemented already).
require('es3-ext/function/#/bind/implement');
function () { return this.x; }.bind({ x: 'foo' })(); // 'foo'
You can also access shims directly, without fixing native objects. Following will return native Function.prototype.bind
if it's available and fallback to shim if it's not.
var bind = require('es3-ext/function/#/bind');
bind.call(function () { return this.x; }, { x: 'foo' })(); // 'foo'
If you want to use shim unconditionally (even if native implementation exists) do:
var bind = require('es3-ext/function/#/bind/shim');
bind.call(function () { return this.x; }, { x: 'foo' })(); // 'foo'
Function.prototype.bind
->require('es3-ext/function/#/bind')
Limited version of ECMAScript's Date.parse
. Return date object for string representation in ISO 8601 format. Returns NaN
if format matches but requested date is invalid. undefined
if string format doesn't match ISO 8601
Introduced with ECMAScript 5.
The bind() method creates a new function that, when called, has its this keyword set to the provided value, with a given sequence of arguments preceding any provided when the new function is called. See: MDN: Function.prototype.bind
