> There are a lot of reasons why typescript sucks for library developers, but at the end of the day it reduces developer productivity. In effect, we are shifting complexity from end-developers to library developers. Isn't that the whole point of libraries? Instead of having a hundred end-users trying to understand a library's untyped API, we save overall developer time by having just the one library developer type its API.
