TypeScript is a typed superset of JavaScript with the potential to solve many of the headaches for which JavaScript is famous. But TypeScript has a learning curve of its own, and understanding how to use it effectively can take time. This book guides you through 62 specific ways to improve your use of TypeScript.

As a long-time JavaScript developer, but as someone relatively new to TypeScript, this book was the right thing at the right time for me. I didn’t need an introductory-level book — TS being a superset of JS, after all, and syntax being something you can muddle through — but what I DID need was something that spoke to what was (1) idiomatic and (2) could shine a light on some of TS’s… idiosyncrasies.

This book helped me better frame my thinking around the so-called “type space” vs. the runtime cod

The book structured into several areas, each presents you with a series of specific tips (the autor has listed the areas and tips on his GitHub). It assumes reasonable knowledge of both modern JS and TS. It definitely isn't a comprehensive intro to TS.

It dedicates about 1-4 pages to each tip, including motivation and detailed explanation with code samples. The writing is easy to understand and avoids any detours/asides and filler; all the code samples are clear and compact (none go past half-pag

The author posted about this book on reddit, and it looked good so I bought a copy straight away. Nice job, Dan!

The book is mostly very good. I've been using TypeScript for 3 years now, so it mostly wasn't so new to me, but it did clarify a lot of the things I knew. In particular, as I haven't read a whole lot of TypeScript code, the convention of using discriminated unions was new to me, and I hadn't really understood how well TypeScript supports it.

I did think the description of transitive dep

I use Typescript for few years already and I find this book really great if you have some experience with TS.

It will be rather poor choice for super beginners (however might be ok if you migrate from C# and you learn it in parallel with JS), but TS users can find a lot of understanding of TS best practices

It has nice structure of "pro tips" - you can skip part which is obvious to you.

Also it has a chapter how to migrate legacy codebase to TS.

It definitely helped me and I used some of the protips

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

We read the introduction and that probably was our limit. But I am fond of the author and very proud of his work and thus am rating this book five stars.

Great book! I thought I knew a lot about TypeScript already, but this book has some tips I did not know before and not readily found on the internet.

I really enjoyed the format. The short sections provided illustrating examples and just enough detail. Every time I put the book down, I felt like I had learned something I could apply immediately.

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

I absolutely love it. It explained a couple of things I didn’t understand and generally has good advice.

It’s a great second TypeScript book.

Interesante libro con muchas cosas que no conocía de Typescript. Muchas veces empezamos a tocar tecnologías que no conocemos y vamos aprendiendo sobre la marcha (haciendo mal las cosas) y este libro ha un vistazo rápido pero profundo de lo que Typescript tiene a tu disposición

Most of part of the book is useful information, however, this information is already well known by developers who work with typescript.

Finally, finish this fantastic book after a few months. I think this kind of book need times to digest and apply to my day-to-day task. An excellent resource for TypeScript!
