Javascript array sort

How to sort array or objects?

JS array sort

// Array of object
const cars = [
    {make: 'Ford', model: 'Mondeo', gearbox: 'manual', year: 2016},
    {make: 'VW', model: 'Passat', gearbox: 'automatic', year: 2014},
    {make: 'Volvo', model: 'XC90', gearbox: 'automatic', year: 2012}
]

//Sort the cars by year, newest to oldest
const ordered = cars.sort(function(a, b) {
  return a.year < b.year;
});

console.table(ordered);

ES6 syntax

const ordered_es6 = cars.sort((a, b) => (a.year < b.year));

console.log('ES6');
console.table(ordered_es6);
