I come from a place that I'm pretty familiar with TypeScript before reading this book. But it was a great experience learning more about this language in depth.
The first chapter was awesome in a way that the book shows more about language than simply about the syntax. It talks about the relationship between JavaScript and TypeScript, how does the structural typing works, the differences between the type and value spaces.
The second chapter talks more about how TypeScript can improve the developer experience together with a code editor.
The following chapters are about how we can use types to be more effective.
I used this book as a reference to write my long-format essay about A Mental Model to think in TypeScript (https://leandrotk.github.io/tk/2020/07/a-mental-model-to-think-in-typescript/index.html).
I really recommend this book for beginners and experienced developers.
