#### ECMAScript 5 features

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).

``javascript
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.

`javascript
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:

`javascript
var bind = require('es3-ext/function/#/bind/shim');
bind.call(function () { return this.x; }, { x: 'foo' })(); // 'foo'
`

#### parse(str) _(es3-ext/date/parse)_

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

#### fn.bind(context[, …args]) _(es3-ext/function/#/bind)_

_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
