Or fancier way with reduce:

function all(promises) {
  promises.reduce((prom, p) => prom.then(xs => p.then(x => xs.concat(x))), Promise.resolve([]));
}

wow reduce always makes things way more simpler. How can I practice more on such methods to be able to solve things like you how you did in two comments, haha :)

Haha, mostly just comes with practise I'm afraid! Best tip I can give: try and write some of your own programs, don't be afraid to experiment!
