array.prototype.values

An ES2015 spec-compliant Array.prototype.values 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 spec.

Because Array.prototype.values depends on a receiver (the “this” value), the main export takes the array to operate on as the first argument.

Example

var values = require('array.prototype.values'); var assert = require('assert'); var iterate = require('iterate-iterator');

assert.deepStrictEqual(iterate(values([1, 2, 3])), [1, 2, 3]); assert.deepStrictEqual(iterate(values([1, 0, 1])), [1, 0, 1]); assert.deepStrictEqual(iterate(values([NaN])), [NaN]); assert.deepStrictEqual(iterate(values([1,,3])), [1, undefined, 3]);

var values = require('array.prototype.values'); var assert = require('assert'); /* when Array#values is not present */ delete Array.prototype.values; var shimmedMap = values.shim(); assert.deepStrictEqual(shimmedMap, values.getPolyfill()); assert.deepStrictEqual(iterate([1, 2, 3].values()), [1, 2, 3]); assert.deepStrictEqual(iterate([1, 0, 1].values()), [1, 0, 1]); assert.deepStrictEqual(iterate([NaN].values()), [NaN]); assert.deepStrictEqual(iterate([1,,3].values()), [1, undefined, 3]);

var values = require('array.prototype.values'); var assert = require('assert'); /* when Array#values is present */ var shimmedMap = values.shim(); assert.equal(shimmedMap, Array.prototype.values); assert.deepStrictEqual(iterate([1, 2, 3].values()), [1, 2, 3]);
