Front end library type definitions are a nightmare because they are usually retrofitted onto code that uses JavaScript idioms that take heavy advantage of metaprogramming and it's dynamic nature. It's also compounded (in my opinion) by developers that insist on making everything inferable instead of just putting a few generic parameters here and there and saving an enormous amount of complexities. Native typescript libraries are generally extremely easy to work with, however.
