We are getting closer and closer to launching the Creative Javascript Course. I wanted to share a small portion of the Async Javascript chapter of the course where we will learn everything there is to know about how async code works in javascript.
We are going to take a look at all the popular ways async code is being run such as callbacks, promises and the new async await.

The video is very well organized, he talks about default async behaviour of JavaScript and the issues with it. He starts with a very basic way of fixing things around using callbacks and elaborate on it using promises and finally with syntactic sugar with Async Await. Thanks for the video :)

I think you should make a full Javascript course sometime soon because I somehow grasp everything you teach maybe just because of your approach and your vibes. Just want to say wish you all the best and keep doing this awesome work!

Just one thing, the asynchronous code is pushed to the webapi stack and when it’s done, it’s pushed by the event loop to the call stack again. So, you didn’t speak about the event loop I guess…
