README

array.prototype.every

An ES5 spec-compliant Array.prototype.every 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 proposed spec.

Because Array.prototype.every depends on a receiver (the ?this? value), the main export takes the array to operate on as the first argument.

Example

every = require('array.prototype.every');
assert = require('assert');

rt.equal(true, every([1, 1, 1], function (x) { return x === 1; }));
rt.equal(false, every([1, 0, 1], function (x) { return x === 1; }));

s
every = require('array.prototype.every');
assert = require('assert');
hen Array#every is not present */
te Array.prototype.every;
shimmedEvery = every.shim();
rt.equal(shimmedEvery, every.getPolyfill());
arr = [1, 2, 3];
lessThan4 = function (x) { return x < 4; };
rt.deepEqual(arr.every(lessThan4), every(arr, lessThan4));

s
every = require('array.prototype.every');
assert = require('assert');
hen Array#every is present */
shimmedEvery = every.shim();
rt.equal(shimmedEvery, Array.prototype.every);
rt.deepEqual(arr.every(lessThan4), every(arr, lessThan4));
