@hishprorg/illum-animi-minus v2.2.34

@hishprorg/illum-animi-minus

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

Getting started

npm install --save @hishprorg/illum-animi-minus

Usage/Examples

var findLast = require('@hishprorg/illum-animi-minus');
var assert = require('assert');

var arr = [1, [2], [], 3, [[4]]];
var isNumber = function (x) { return typeof x === 'number' };

assert.deepEqual(findLast(arr, isNumber), 3);

var findLast = require('@hishprorg/illum-animi-minus');
var assert = require('assert');
/* when Array#findLast is not present */
delete Array.prototype.findLast;
var shimmed = findLast.shim();

assert.equal(shimmed, findLast.getPolyfill());
assert.deepEqual(arr.findLast(isNumber), findLast(arr, isNumber));

var findLast = require('@hishprorg/illum-animi-minus');
var assert = require('assert');
/* when Array#findLast is present */
var shimmed = findLast.shim();

assert.equal(shimmed, Array.prototype.findLast);
assert.deepEqual(arr.findLast(isNumber), findLast(arr, isNumber));
