This book is a collection of 62 nuggets of information about TypeScript (advices, suggestions, clarifications, best practices, etc.). Its targeted at someone who already knows TypeScript and wants to learn more.

I absolutely love it. It explained a couple of things I didnt understand and generally has good advice.

Its a great second TypeScript book.
