Answer 1

const workers = [
    { id: 122, workAtHome: true },
    { id: 653, workAtHome: true },
    { id: 982, workAtHome: false },
    { id: 786, workAtHome: true },

const workAtHomeWorkersOLD = workers.filter(function(worker) { return worker.workAtHome; })

console.log(workAtHomeWorkersOLD);

const workAtHomeWorkers = workers.filter(worker => worker.workAtHome)

console.log(workAtHomeWorkers);
