README

array.prototype.some

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

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

rt.equal(true, some([1, 2, 3], function (x) { return x === 2; }));
rt.equal(false, some([1, 2, 3], function (x) { return x === 4; }));

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

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