An ESnext spec-compliant `String.prototype.endsWith` shim/polyfill/replacement that works as far down as ES3.

This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment and complies with the [spec](https://tc39.es/ecma262/#sec-string.prototype.endswith).

Because `String.prototype.endsWith` depends on a receiver (the `this` value), the main export takes the string to operate on as the first argument.

Other polyfills for `String.prototype.endsWith` are available:

* <https://github.com/paulmillr/es6-shim/blob/d8c4ec246a15e7df55da60b7f9b745af84ca9021/es6-shim.js#L175-L184> by [Paul Miller](http://paulmillr.com/) (~~fails some tests: [1](https://github.com/paulmillr/es6-shim/issues/168), [2](https://github.com/paulmillr/es6-shim/issues/175)~~ passes all tests)
* <https://github.com/google/traceur-compiler/blob/315bdad05d41de46d25337422d66686d63100d7a/src/runtime/polyfills/String.js#L39-L66> by Google (~~[fails a lot of tests](https://github.com/google/traceur-compiler/pull/555)~~ now uses this polyfill and passes all tests)

## Installation

Via [npm](http://npmjs.org/):

```bash
npm install string.prototype.endswith
```

Then, in [Node.js](http://nodejs.org/):

```js
var endsWith = require('string.prototype.endswith');
```

```html
<script src="https://bundle.run/string.prototype.endswith"></script>
```

> **NOTE**: It's recommended that you install this module using a package manager
> such as `npm`, because loading multiple polyfills from a CDN (such as `bundle.run`)
> will lead to duplicated code.

## Notes

Polyfills + test suites for [`String.prototype.startsWith`](https://mths.be/startswith) and [`String.prototype.contains`](https://mths.be/contains) are available, too.
