Convert React JavaScript Code to TypeScript with Proper Typing

My understanding is that now I have to also manage type definitions. It ends up being more code in my files and more files.

I'm a big fan of keeping files as minimal and simple as possible. I virtually "count" the number of language concepts that exist, and try to keep it as low as possible. Makes it easy for other developers to on-board and for me to re-on-board.

you don't actually have to manage type definitions for your own code (unless you're referring to typing parameter/return values), just things that you eg. fetch from the backend. those can be trivially generated by a tool from sample json or you can generate it all from things like OpenAPI.

You don't have to do anything. Just drop TypeScript in as a replacement for babel. Whenever you find yourself wondering if a type annotation or definition would help, then do it. Leave it optional; no commitment required.
