About the Book

This book is an introduction to React, but also dives much deeper into the ideas behind React. Rather than cargo-culting on what is popular, the goal is to show the reader how React works under the hood, as well as go over how to use it. In addition, we will be going over why React is great for working with existing legacy code and third-party libraries such as jQuery plugins. We will also go over advanced techniques for improving performance. By the end of this book the reader should fully understand React's architectural philosophy and design decisions.

To achieve this, the book will be a mixture of explanations and a practical exercise where the reader will build a simple Star Trek video game.
