An ES5 spec-compliant Array.prototype.reduceRight 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.reduceRight depends on a receiver (the “this” value), the main export takes the array to operate on as the first argument.

Example

var reduceRight = require('array.prototype.reduceright');
var assert = require('assert');
 
assert.equal(reduceRight([1, 2, 3], function (prev, x) { return prev + x; }), 6);
assert.equal(reduceRight([1, 2, 3], function (prev, x) { return prev + x; }, 1), 7);
var reduceRight = require('array.prototype.reduceright');
var assert = require('assert');
/* when Array#reduceRight is not present */
delete Array.prototype.reduceRight;
var shimmed = reduceRight.shim();
assert.equal(shimmed, reduceRight.getPolyfill());
var arr = [1, 2, 3];
var sum = function (a, b) { return a + b; };
assert.equal(arr.reduceRight(sum), reduceRight(arr, sum));
assert.equal(arr.reduceRight(sum), 6);
assert.equal(arr.reduceRight(sum, 1), 7);
var reduceRight = require('array.prototype.reduceright');
var assert = require('assert');
/* when Array#reduceRight is present */
var shimmed = reduceRight.shim();
assert.equal(shimmed, Array.prototype.reduceRight);
assert.equal(arr.reduceRight(sum), reduceRight(arr, sum));
