I worked with react before typescript, react with flow, angular 1 (large projects), and these days I mostly use react with typescript.

I don’t use it for css, but for the view components and code I find typescript actually makes me both faster and my code is more reliable. To me this is one of the killer features of react that other libraries are in various stages of catching up to: full static type checking end to end. (Also through the API to the backend with a little more work).
