es-shimsarray.prototype.slice 
An ES spec-compliant Array.prototype.slice shim/polyfill/replacement that works as far down as ES3.
This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec.
Because Array.prototype.slice depends on a receiver (the “this” value), the main export takes the array to operate on as the first argument.

Example
var slice = require('array.prototype.slice');
var assert = require('assert');
var a = [1, 2, 3];
assert.deepEqual(slice(a, 1, 2), [2]);
assert.deepEqual(slice(a, -2), [2, 3]);
var slice = require('array.prototype.slice');
var assert = require('assert');
/* when Array#slice is not present */
delete Array.prototype.slice;
var shimmed = slice.shim();
assert.equal(shimmed, slice.getPolyfill());
assert.equal(shimmed, Array.prototype.slice);
assert.deepEqual([1, 2, 3].slice(1, 2), slice([1, 2, 3], 1, 2));
var slice = require('array.prototype.slice');
var assert = require('assert');
/* when Array#slice is present */
var shimmed = slice.shim();
assert.equal(shimmed, Array.prototype.slice);
assert.deepEqual([1, 2, 3].slice(1, 2), slice([1, 2, 3], 1, 2));
