During my internship we've built a large prototype using React+Typescript, and here are some of my key take aways from it:

  - Quite often when using unreleased APIs, you turn to using "any" all over the place.
  - Development time is slower than writing in regular JS/React. This started to become a major issue due to the nature of our project being a prototype (fast iterations on ideas and features). 
  - Lots of frustration when a package doesn't have types (although most major ones do have them).

Otherwise it has been a joy writing the application, and it does "document" your components significantly better.
