Suppose you're using an editor that actually gives you clever warning if types don't match? Using plain vim with typescript makes no sense. It gives me plenty of useful checks using TS. Lack of members, wrong types returned, missing return in switch statement etc. Saying JS works for you fine sounds like "I have (or waste) good amount of brain memory on my program, so I don't need any further checking.", which can't be the case on code other people wrote.
