Group Array of JavaScript Objects by Keys or Property Values

This fork of JamieMason's implementation changes the key parameter to be an array of keys instead of just a single key. This makes it possible to group by multiple properties instead of just one.

Implementation

const groupBy = keys => array =>
  array.reduce((objectsByKeyValue, obj) => {
    const value = keys.map(key => obj[key]).join('-');

test

	<ul id="pages-block">
	<li v-for="page in pages">
	<a v-bind:href="page.url">{{page.name}}</a>
	<debug :item="page"/>
	</li>
	</ul>

	...

	Vue.component('debug', {

	import { shallowMount } from '@vue/test-utils'
	import AppCheckbox from '@/shared/components/inputs/AppCheckbox'
	import { VueLoaderPlugin } from 'vue-loader';

	describe('AppCheckbox', () => {
	let wrapper
	beforeEach(() => {
	wrapper = shallowMount(AppCheckbox, {
	propsData: {
	value: false,
