An ES5 spec-compliant `Array.prototype.every` shim/polyfill/replacement that works as far down as ES3.
This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment and complies with the proposed [spec](https://www.ecma-international.org/ecma-262/6.0/).
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
```js
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; }));
``````js
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));
``````js
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));
