A good introduction in Typescript & ES6+.

[Mark Nenadov · Rating 5 out of 5]

This is an excellent book if you want to get to get to know Typescript. It's written with attention to detail, plenty of solid examples, and gives a pretty good deep dive. I know it's a small thing, but I also appreciated the variety of quotes from old software development luminaries (you just don't expect that sort of thing in a JavaScript book). There were a couple chapters that weren't very interesting to me, but overall, when discussing the core topic, this book was very helpful.

There were several good things I have taken away from this book, but it still feels a bit padded, although if you wanted not only TS but a lot of JS, you will find it here. Though I would have preferred a shorter read.

I started reading this book, after I started working with Angular 2. First time when I saw Angular 2 (most of the time I worked with PHP and I'm more like a backend developer) I was like wtf, I can't follow anything and why the things are so complicated, but in a fact I was unaware how JavaScript progressed. So, to start with Angular 2, I decided to dig a bit into TypeScript and this book was the perfect shoot.

The book gives you an overview about TypeScript, pros and cons, and starts immediately with some really good examples and explanations. Lot of the story I just re-learned (lot of the things are almost the same as in C language), and after reading first three chapters you will be able to follow Angular 2 official tutorials and you will understand what is happening there.

I can only recommend this book.

This is a phenomenal book. One of the best programming books I have ever read. If you want to learn TypeScript, this is the book. I'm only mildly familiar with JavaScript, and this book was perfect for me. Absolutely brilliant. Clear, concise, easy to read, well-written. Just an all around excellent book.

Fenton has written a good, concise, and thorough-enough introduction to TypeScript for the experienced programmer. A wide range of topics are covered, some only enough to give one familiarity as they dig into the topic themselves. Some guidance on idiomatic TS and best practices was appreciated, and even more discussion of these things--especially at scale--would have been appreciated. I'll definitely be reviewing my notes of this book soon. Recommended, if you want to get up to speed quickly on TypeScript and you have a decent amount of JavaScript grounding.

Loved it - concise yet insightful

Really feels like I got my money's worth. The author get straight to the point without leaving you feeling like he's leaving anything out. Easy to follow along - truly a great read.

Good overview of Typescript, which is a big boost for JavaScript.

[Clark · Rating 5 out of 5]

Awesome book, Steve goes into many more subjects than what you expect from a book on TypeScript

[Ondrej Sykora · Rating 4 out of 5]

This is a comprehensive overview of TypeScript features and some development practices.

The book was quite dry to read, and might be incomprehensible to those who are not familiar with (modern) JavaScript development, as it references JS features, but doesn't really stop to explain them. If you're a JS programmer who wants to convert, this is probably a good book. But if you want to get started with web development and want to skip the JS stage, look elsewhere.

[Harvey · Rating 4 out of 5]

This is a good intro to TypeScript. All of it had value, but as the lines blur between JavaScript and TypeScript, there are several chapters that I didn't feel were needed in this volume. They contained standard JavaScript concepts available elsewhere.

[Fatih · Rating 4 out of 5]

You should know about Typescript because book has advanced topics. Some examples are poor content . Only one reading is not enough for this book. You can need one more reading. I recommend this book for frontend developer using javascript frameworks.
