How to group an array of JavaScript objects by key or property value

I first came across this code on JamieMason's gist. Here I've tried to re-create it from scratch as I found their solution slightly hard to follow.

Implementation

function groupBy(key) {
  return function group(array) {
    return array.reduce((acc, obj) => {

// file: controller.js

const databaseUpdater = require('../model/databaseUpdater');
// ^ This is out model function that goes and updates the database.
function updateTotal(total) {
 databaseUpdater({ body: total });
}
function calculateTotal(data) {
 const total = data.reduce((accumulator, number) => accumulator + number, 0);
 updateTotal(total);

const proxyquire = require('proxyquire');
const sinon = require('sinon');
const chai = require('chai');
const { expect } = chai;

describe('calculateTotal', function(done) {
 it('calculates the total and updates the database', function() {

Work in progress to scrap https://httpstatuses.com/ for snippets about status codes.

const fetch = require('node-fetch');
const cheerio = require('cheerio');

const STATUS_CODES = [200, 201, 400, 500];

const URL = 'https://httpstatuses.com';

Using the raspberry pi zero w with an inkyphat e-ink display

Hey,

My name's Nikhil. I'm a JavaScript developer who doesn't know any python - I hacked this script together till I got something I liked due to just wanting something that worked, and haven't touched this code since due to having a thing that worked. If you end up improving it, I'd really appreciate a shout.

I've written a post about it here https://nikhilvijayan.com/raspberry-pi-zero-weather-display.
