React is an open source, adaptable JavaScript library for building complex user interfaces from small, detached bits called components. This book will help you to use React effectively to make your applications more flexible, easier to maintain, and improve their performance while giving your workflow a huge boost by improving speed without affecting quality.

You'll start by understanding the internals of React, before gradually moving on to writing maintainable and clean code. The chapters that follow will show you how to build components that are reusable across the application, how to structure applications, and how to create forms that actually work. Later, you will build on your knowledge by exploring how to style React components and optimize them to make applications faster and more responsive. Finally, you'll learn how to write tests effectively and learn how to contribute to React and its ecosystem.

By the end of this book, you'll be able to avoid the process of trial and error and developmental headaches, and instead have the skills you need to efficiently build and deploy real-world React web applications.
