An ES spec-compliant `Array.prototype.forEach` 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-array.prototype.foreach).

Because `Array.prototype.forEach` depends on a receiver (the `this` value), the main export takes the array to operate on as the first argument.

## Getting started

```sh
npm install --save array.prototype.foreach
```

## Usage/Examples

```js
var forEach = require('array.prototype.foreach');
var assert = require('assert');

var arr = [1, [2], [], 3, [[4]]];
var counter = 0;
var increaseCounter = function (x) { counter += 1; };

assert.equal(forEach(arr, increaseCounter), undefined);
assert.equal(counter, arr.length);
```

```js
var forEach = require('array.prototype.foreach');
var assert = require('assert');
/* when Array#forEach is not present */
delete Array.prototype.forEach;
var shimmed = forEach.shim();
var counter = 0;

assert.equal(shimmed, forEach.getPolyfill());
assert.equal(arr.forEach(increaseCounter), forEach(arr, increaseCounter));
assert.equal(counter, arr.length * 2);
```

```js
var forEach = require('array.prototype.foreach');
var assert = require('assert');
/* when Array#forEach is present */
var shimmed = forEach.shim();
var counter = 0;

assert.equal(shimmed, Array.prototype.forEach);
assert.equal(arr.forEach(increaseCounter), forEach(arr, increaseCounter));
assert.equal(counter, arr.length * 2);
```
