Typescript is not suitable for all applications. I also transitioned to Typescript from python some years ago and the extra information about "intent" provided by types made a world of difference to me when reading code written by other people. Type information is so valuable in a team of 3+ developers and when a rest api has at least 5+ resources. If your application or team size are any less, the benefits of typescript might not be obvious. I think that could be what you're experiencing.

In a team, it is just so much easier to come across a "typed" function as opposed to an untyped one. You need to read the entire function to know what it is about.
