An ES5 spec-compliant Array.prototype.filter 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.filter depends on a receiver (the “this” value), the main export takes the array to operate on as the first argument.

Example

var filter = require('array.prototype.filter');
var assert = require('assert');

assert.deepEqual(filter([1, 2, 3], function (x) { return x >= 2; }), [2, 3]);
assert.deepEqual(filter([1, 2, 3], function (x) { return x <= 2; }), [1, 2]);
var filter = require('array.prototype.filter');
var assert = require('assert');
/* when Array#filter is not present */
delete Array.prototype.filter;
var shimmedFilter = filter.shim();
assert.equal(shimmedFilter, filter.getPolyfill());
var arr = [1, 2, 3];
var isOdd = function (x) { return x % 2 !== 0; };
assert.deepEqual(arr.filter(isOdd), filter(arr, isOdd));
var filter = require('array.prototype.filter');
var assert = require('assert');
/* when Array#filter is present */
var shimmedFilter = filter.shim();
assert.equal(shimmedFilter, Array.prototype.filter);
assert.deepEqual(arr.filter(isOdd), filter(arr, isOdd));
