Opinion
It was one of my earliest encounters with TypeScript, one that stayed mostly positive, although the material is quickly forgotten without practice. However, thanks to a substantial set of notes, the core concepts and language features can always be recalled. Regarding the book, its content is aimed at an introductory introduction to the language. Almost every feature and trick of TypeScript that existed at the time of publication is covered here. Nevertheless, the material is not particularly in‑depth, nor is there any information on the language’s ecosystem.
