I always found react-redux's connect function maddeningly hard to understand, because it does far too many things all in one function. The types just expose that complexity, and make it plainly obvious that it should be split apart.

The great thing about types is that the make you think more about keeping you APIs nice and clean on a semantic level, not just about if the syntax in your examples look pretty. I really hope more library authors use them early on so they avoid such mistakes in the future. There's only so much the Flow and TypeScript devs can do to make up for those existing problems.

Which gets to my wish that instead it is the React team themselves that adopt and maintain @types/react more directly, rather than leaving it to the community and/or Typescript devs. Seeing CRA add default support for Typescript transpilation with easy opt-in for type checking, is a great sign that plenty more React developers are going to have a chance at Typescript. Hopefully it becomes more of a two-way street where the Typescript community isn't just typing major React libraries after the fact, but more of the libraries are directly written in Typescript or at least the types are directly maintained by the authors of the APIs.
