An ES spec-compliant `TypedArray.prototype.slice` shim. Invoke its "shim" method to shim TypedArray.prototype.slice if it is unavailable.

This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES5-supported environment and complies with the [spec](https://tc39.es/ecma262/#sec-%typedarray%.prototype.slice).

Most common usage:
```js
var assert = require('assert');
var slice = require('typedarray.prototype.slice');

var arr = new Uint8Array([1, 2, 3]);

var arr2 = slice(arr);

arr2[0] = 2;
arr2[1] = 3;

assert.deepEqual(arr, new Uint8Array([1, 2, 3]));
assert.deepEqual(arr2, new Uint8Array([2, 3, 3]));
assert.notEqual(arr.buffer, arr2.buffer);

if (!Uint8Array.prototype.slice) {
	slice.shim();
}

var arr3 = arr.slice();
arr3[0] = 2;
arr3[1] = 3;

assert.deepEqual(arr, new Uint8Array([1, 2, 3]));
assert.deepEqual(arr3, new Uint8Array([2, 3, 3]));
assert.notEqual(arr.buffer, arr3.buffer);
```

## Engines where this is needed

	- node v0.11.4 - v4: no prototype or own `slice` method
	- node < v0.11.3: own `slice` method that fails to clone the underlying buffer

## Tests
Simply clone the repo, `npm install`, and run `npm test`
