The entire “Asynchronous JavaScript” module of JavaScript for Everyone is now free

Original author: Mat “Wilto” Marquis

Commentary: Andy Bell

One element of JavaScript that people struggle with the most is asynchronous JavaScript. Y’know, “Why is my fetch returning this in the console?” for example.

Try it out


function myPromise() {
  const req = fetch('/');

  console.log(req);
}

Oh yeh, the async and await were missing!

Try it out


async function myPromise() {
  const req = await fetch('/');
  
  console.log(req);
}

Mat gets really deep into how all this stuff works. You’re not just learning how promises work, for example. You’re learning all the deep parts that make them work like the do.

These free lessons — including this one and this one — will give you a real flavour of how damn good he is at teaching JavaScript too.
