React is a JavaScript library for building efficient and extensible web applications. React is developed by Facebook and is used in many large-scale web applications, such as Facebook, Instagram, Netflix, and WhatsApp Web.

React Hooks were introduced in the React 16.8 release and solve many common problems with React projects. Hooks make components less complex, more concise, and easier to read and refactor. Furthermore, they make many React features much easier to use and understand, and we avoid having to use wrapper components.

This book is the definitive guide to learning React Hooks. You are going to learn all the facets of React Hooks for managing state and effects in React components, as well as using other React features, such as context, via Hooks. With practical examples, you are going to learn how to develop large-scale and efficient applications with code that is extensible and easy to understand.

The book also delves into advanced concepts, such as using Hooks in combination with libraries like Redux and MobX. Furthermore, you are going to learn when and how existing projects can be efficiently migrated to React Hooks.
