The best primer for the event loop I have found is here: [this video] The speaker (Jake Archibald) has that rare ability to be both likeable and relatable, while also being incredibly knowledgeable and enthusiastic. I wish a lot more talks were like this!

I've been struggling with wrapping my head around asynchronous programming with callbacks, promises and async/await in JS, however I think it's finally clicking after watching these YouTube videos and creating a document where I explain these concepts as if I'm teaching them to someone else: * Philip Roberts's What the heck is the event loop anyway? - [LINK] * The Story of Asynchronous JavaScript - [LINK] * JavaScript Callbacks, Promises, and Async / Await Explained - [LINK] * Async Javascript Tutorial For Beginners (Callbacks, Promises, Async Await). - [LINK] * Jake Archibald: In The Loop - setTimeout, micro tasks, requestAnimationFrame, requestIdleCallback, - [this video] Edit...

Pro: you can’t hang any given task from a single thread; con: shared memory is very difficult to impossible, as you never know when you’ll be interrupted. Browser JavaScript and UI interactions instead use cooperative multitasking, which you’ll also find in classic Mac OS, 16-bit Windows, basically every embedded system ever
