About The Book
First, the book gently explores TypeScript, from basic ideas to common techniques and advanced strategies. Then, right around the midpoint, we'll take the leap into structural type systems and why they are so useful for your work.
We'll dive into working with types, typing functions, union and intersection types, generics, conditional types and wrap up with thinking in types.

Table Of Contents
Programming books have a tendency to become outdated very quickly. When Stefan set out to write this book, his most important goal was that it had to be timeless. TypeScript gets at least two major releases a year, so there are new features and changes coming regularly.
That’s why the book focuses on the long-lasting aspects of the type system. You'll understand how TypeScript works, and how to apply new features long after you've turned the last page of this book.
The book is split into 7 chapters.
- 1. TypeScript for Smashing People+
- 2. Working with Types+
- 3. Functions+
- 4. Union and Intersection Types+
- 5. Generics+
- 6. Conditional Types+
- 7. Thinking in Types+
“Stefan Baumgartner’s book finally made me want to use TypeScript. Until now, I didn't understand why I should use TypeScript. Without knowing the core principles, it made things more complicated for me. After reading this book, I know how to use the power of TypeScript to my advantage.”
— Vanessa Böhner, Software Developer and Chapter Leader at Front-End Foxes
“Stefan walks you through everything from basic types to advanced concepts like the
inferkeyword in a clear and easy to understand way. The book is packed with many real world examples and great tips, transforming you into a TypeScript expert by the end of it. Highly recommended read!”
— Marvin Hagemeister, Creator of Preact-Devtools

Code Snippets and Hands-On Examples
TypeScript in 50 Lessons is a very practical book. It features lots of examples that not only give you an idea about syntax and semantics, but show you actual use-cases that you might encounter in your applications.
To help you follow the code examples in the book, Stefan has set up projects on Code Sandbox and the TypeScript playground, where you can fiddle around on your own and see how the TypeScript's type system behaves. You'll find all code snippets on the TypeScript book website.
