Simple ES6 [Array.prototype.find](http://people.mozilla.org/%7Ejorendorff/es6-draft.html#sec-array.prototype.find) polyfill for older environments taken from [es6-shim](https://github.com/paulmillr/es6-shim).

For browsers and node.js.

## Installation

* Just include repo before your scripts.

* `npm install array.prototype.find`

## Usage

* `Array.prototype.find(predicate[, thisArg])` returns first item that matches `predicate` function.

* `predicate(value, index, collection)`: takes three arguments

    * `value`: current collection element

    * `index`: current collection element index

    * `collection`: the collection

```javascript

// as a function

var find = require('array.prototype.find');

find([1, 2], function (x) { return x === 2; }); // 2

// to shim it

require('array.prototype.find').shim();

```

Code example:

```javascript

// Default:

[1, 5, 10, 15].find(function (a) { return a > 9; }) // 10

```
