Package Exports

array.prototype.every
array.prototype.every/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (array.prototype.every) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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

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));
