Chapter 1, Introducing React and UI Design, introduces React and helps us to start building the basic infrastructure of a React-based application. Then, we will analyze how to design a user interface so that it can be easily mapped to React components.

Chapter 2, Creating Components, teaches us how to implement React components, how to assemble multiple components into one, and how to manage their internal states. We will explore React component implementation by building a simple application.

Chapter 3, Managing User Interactivity, teaches us how to manage the events generated by a user's interaction with the components of a React-based user interface. We will explore the events that are triggered during the lifecycle of a React component, and will learn how to exploit them in order to create efficient components.
