An ES5 spec-compliant `Array.prototype.some` 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 proposed [spec](https://www.ecma-international.org/ecma-262/6.0/).

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

## Example

```js

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

var assert = require('assert');

assert.equal(true, some([1, 2, 3], function (x) { return x === 2; }));

assert.equal(false, some([1, 2, 3], function (x) { return x === 4; }));

```

```js

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

var assert = require('assert');

/* when Array#some is not present */

delete Array.prototype.some;

var shimmedSome = some.shim();

assert.equal(shimmedSome, some.getPolyfill());

var arr = [1, 2, 3];

var threeOrLarger = function (x) { return x >= 3; };

assert.deepEqual(arr.some(threeOrLarger), some(arr, threeOrLarger));

```

```js

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

var assert = require('assert');

/* when Array#some is present */

var shimmedSome = some.shim();

assert.equal(shimmedSome, Array.prototype.some);

assert.deepEqual(arr.some(threeOrLarger), some(arr, threeOrLarger));

```
