Understanding HTTP/3: Is It Really Better Than HTTP/2?

No wonder most devs record one trace, get scared, and go back to console.log debugging. I did exactly that for years - until I actually sat down and learned what each piece means, and now it’s the first tool I reach for when something “feels slow.”
