Package Exports
- array.prototype.some
- array.prototype.some/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.some) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
An ES5 spec-compliant Array.prototype.some
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.some
depends on a receiver (the “this” value), the main export takes the array to operate on as the first argument.
Example
var some = require('array.prototype.some');
var assert = require('assert');
assert.equal(true, some([1, 2, 3], function (x) { return x === 2; }));
assert.equal(false, some([1, 2, 3], function (x) { return x === 4; }));
var some = require('array.prototype.some');
var assert = require('assert');
/* when Array#some is not present */
delete Array.prototype.some;
var shimmedSome = some.shim();
assert.equal(shimmedSome, some.getPolyfill());
var arr = [1, 2, 3];
var threeOrLarger = function (x) { return x >= 3; };
assert.deepEqual(arr.some(threeOrLarger), some(arr, threeOrLarger));
var some = require('array.prototype.some');
var assert = require('assert');
/* when Array#some is present */
var shimmedSome = some.shim();
assert.equal(shimmedSome, Array.prototype.some);
assert.deepEqual(arr.some(threeOrLarger), some(arr, threeOrLarger));
