    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

    var every = require('array.prototype.every');
    var assert = require('assert');
    
    assert.equal(true, every([1, 1, 1], function (x) { return x === 1; }));
    assert.equal(false, every([1, 0, 1], function (x) { return x === 1; }));
    var every = require('array.prototype.every');
    var assert = require('assert');
    /* when Array#every is not present */
    delete Array.prototype.every;
    var shimmedEvery = every.shim();
    assert.equal(shimmedEvery, every.getPolyfill());
    var arr = [1, 2, 3];
    var lessThan4 = function (x) { return x < 4; };
    assert.deepEqual(arr.every(lessThan4), every(arr, lessThan4));
    var every = require('array.prototype.every');
    var assert = require('assert');
    /* when Array#every is present */
    var shimmedEvery = every.shim();
    assert.equal(shimmedEvery, Array.prototype.every);
    assert.deepEqual(arr.every(lessThan4), every(arr, lessThan4));
