Asynchronous JavaScript: Promises and the event loop
In this lecture we build the mental model that everything else in asynchronous JavaScript rests on: the call stack, the web APIs environment, the callback queue and the microtask queue. You will trace a real script line by line and predict the exact output order before running it.
Asynchronous JavaScript
console.log('A');
setTimeout(() => console.log('B'), 0);
Promise.resolve().then(() => console.log('C'));
console.log('D');
Certificate of completion
Anyone can confirm this certificate without an account, using the ID above.

I'm a full-stack web developer and designer with a passion for teaching. My mission is to make web development accessible and enjoyable for everyone — I focus on how things actually work under the hood, because that is what turns a tutorial-follower into a developer.
I started teaching online in 2015. Since then my courses have been taken by more than 1.8 million students across 190 countries, and translated into 37 subtitle languages.
