Google "the problem with typescript", there are people who don't like it. I don't know how many they are but saying "no one" is silly.

I broadly prefer JavaScript to TypeScript. TypeScript has it's place and is certainly useful in some scenarios (it's union type is so powerful) but I don't think I'd ever plan on coding exclusively in it. I've written code in OCaml and Rust too so I know what a good type system can do.

I think at least for UI work there is a lot of space for dynamic plumbing together of well typed components. Components in this case meaning actual UI components as well as modules of business logic or state management.

You need to get out more. =)

I only use TypeScript on projects written from scratch for TypeScript, like Angular.

On personal projects I only want to deal with builtin browser technologies, there is no npm, webpack, tsc, yarn, whatever, just plain <script/> tags.

I have never wanted to go TypeScript in first place.
