es-shimsTypedArray.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('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
