Making Sense Of The JavaScript Event Loop

The Event Loop. The Stack. The Queue. The Heap. What are they? Does it matter? And most importantly... why does JavaScript insist on being so bizarre? Code is so hard to debug, it's running into itself... does it make any sense? In this computer science Thursday video, I'll show you it does! The event loop is not only an essential part of the JavaScript paradigm, it's what makes it so powerful!

so I can remember, It's going to execute what's in the Stack then Micro Task queue then Callback queue.
I think this is one of the best explanations I have ever watched/read (or maybe it became easier to understand after watching/reading about it over and over again)

Thanks Rob!

An absolutely amazing video. You explain very well. Thank you !
Something like this maybe about the weird types things (you know int + str) (float things, etc) in JS (just an idea).
