TypedArray.prototype.slice

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 interface. It works in an ES5-supported environment and complies with the spec.

Most common usage:

var assert = require('assert');
var slice = require('@micromint1npm/mollitia-consequuntur-perferendis');

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
