do you think javascript was just too easy and people had to invent some bs to make it more interesting for no reason? You don't even know what you're talking about when you make the connection from ts to oop.
My experience comming into javascript is that it's a garbage language and the web stack was a joke, everything was hard for the wrong reason (css centering things kinda stuff)
All these modern tooling, though complicated, is not new in NORMAL programming and makes sense, so you cow boys learn to deal with it.
