> - add JSdoc tags so that IntelliJ can detect type mismatches.

Yes, it's so awesome when colleagues writing lots of useless stuff into the code so they IDE can show some fancy popups here and there.

Yeah, truly useless... I mean, why would you spend $0.0001 dollars in computing power to verify all types in your program if you can spend orders of magnitude more money to have a human do it by hand orders of magnitude slower and less reliably?

Nobody has money for that. Just add the type annotation and let the stupid computer do it, which is what people have been doing for decades anyways.

It seems you have totally forgotten what computers are for. You have much to learn, young padawan.
