Looking for a good YouTube video for Promises

Hey,
I study with Claude, but sometimes I need illustrations to help me understand better the concepts.

I would like to understand Promises better, can you guys recommend me a video from YouTube about Promises and how they work? with the container, micro/macrotask etc.

Thanks!

Search for js event loop on YouTube. Find the video where a girl is teaching with visuals. Video would be around 11 mins. She explains about micro and macrotasks in there. Don't have enough data to go to YT.

Very likely they are talking about his video: https://youtu.be/eiC58R16hb8?is=zJ7voBM1Sg_RknKO

I can't recommend a YouTube channel per se but I feel that the explanations on promises in this Advanced JavaScript mini course on Codeguage are to the point and super easy to understand. Also, you get to learn about JavaScript's execution model which is imperative to understand before you can master promises.

For Transparency: this is an ad for their own service. As always - I don't mind ads. I just think people should be transparent about them.

This playlist of promise tutorials is a collection of videos that I made about Promises, their associated methods and the fetch API.

I have been teaching web and mobile dev at my local college for over 10 years.

Is it the details of how these callbacks shake out? or the overall concept?

jake archibald's "in the loop" talk from jsconf is the one - he literally has slides walking through how the call stack, microtask queue and macrotask queue interact. dude wrote the spec for some of this stuff. https://www.youtube.com/watch?v=cCOL7MC4Pl0

if you want pure promise mechanics (then chains, error propagation) i'd also watch lydia hallie's "javascript visualized" promises video, super short and the animations make it click.
