TypeScript in 50 Lessons

Every other day, one of your team members makes a case for switching from “chaotic” JavaScript to “sane” TypeScript. Maybe you rely on not-very-well-understood JavaScript libraries, or you have a large number of contributors, or the code base is difficult to maintain. The reasons are always similar, but so is the hesitance from the team. Why change the stack that seems to be working just fine?

That’s the question we’ve asked ourselves as well. So we’ve teamed up with Stefan Baumgartner, a seasoned JavaScript developer drawn to TypeScript for years, to break it all down into understandable pieces. The result is TypeScript in 50 Lessons — our shiny new book, with everything TypeScript explained, from start to finish.

WHO IS THIS BOOK FOR?

It’s for developers who know enough JavaScript to be dangerous. If you are spending an increasing amount of time programming and want to be more productive, that’s the book you. With TypeScript, you can get more out of your JavaScript code – for yourself and your colleagues.

The book is also for developers who dipped their toes into TypeScript and now want to get their feet wet. If you want to learn about type systems and how they can be used to define complex JavaScript scenarios, this book will help you, too. This knowledge will ultimately become language-independent, preparing you for different programming languages that have elaborate type systems.

If you ever find yourself:

• writing JavaScript with libraries and frameworks you barely know
• writing JavaScript with other developers
• writing JavaScript that deals with back-end data
• writing JavaScript that your future self has to continue working on

…then TypeScript will do right by you.
