Typescript may not be for you, but what your saying doesn't make any sense. You sound like you work alone more often. I remember getting a snippet of js and not having a clue what was what. I was like console log the variables and send it to me. I remember getting typescript code and instantly knew everything that was going on. So static languages are for static analysis, it's not about run time type checking for typescript.
Typescript makes code readable because it describes the content of the code in the lease possible way, compared to using jsdoc, and typed js has been proven to have less bugs. It's not typing that slows development it's bugs. Look it up
