JavaScript the Hard Parts: Async & Promises

Our mental models of asynchronicity in javascript - the event loop, callback queue - are no longer enough. We have to augment them with the new world of native promises and async/await and understand them intuitively. In this session, Reid will cover this so you can write readable code and debug effectively.

Reid will cover:
- The challenge with single-threadedness in JavaScript.
- How asynchronicity enables much of modern web development
- The challenge with asynchronicity in JavaScript and how promises fix the problem of inversion of control

I just wanna clarify one thing. Reid said at 47:05 that setTimeout is part of JS engine. This is not true. it is web browser api (to be more specific - timer api) same as fetch, local storage etc.

This lecture was amazing, I was always confused with this topic, but Reid Klasfeld explained the topic very well.

Thank you for making such difficult topics so easy and interesting to learn!

I can't say how helpful these vidoes are. But we want to see more. It would be awsome if shared videos about other JavaScript topics like DOM. Thanks a lot

Would be nice if you'd record the video and audio separately from the online class he gives, since it is very hard to watch/listen to jittery material. I am especially sensitive to it, so it is almost impossible for me to get through this.
