@abstracted.away: JavaScript can only do ONE thing at a time. So how does it handle: 🌐 Network requests ⏰ Timers 🖱️ User clicks ...without freezing? The answer is the Event Loop. A surprisingly simple idea that powers asynchronous JavaScript. Once this clicks, a lot of "weird" JavaScript behavior suddenly makes sense. #javascript #coding #computerscience
development lead for 15 years here, and i couldn't explain it more beautifully than you did, hats off

Iframes run in separate threads; we can create hundreds of iframes and execute the same code using parallel threads.

stupid question plz dont hate, why the devs behind JS don't rebuild the language to become multithread?

the answer is that we effectively simulate multi threading with workers 😅

a small little backend app is fine, but the scale will get you in a hell

Oh my god this is single handedly the best video describing how javascripts single threaded event loop works that I've ever seen. Bravo to the creators. As someone who learned java, c++ first, I always had trouble understanding what the point of callbacks and anonymous functions were and how they fit into the greater picture.

So what happens when the call stack never ends but the information from the queue needs to be used

So basically it solves the problem by not solving it and instead letting the API do the actual work while it's busy making things look presentable.

but you have workers for new threads and spawn for new instances (Atleast in bun server side)
