Introduction

In the previous section, you learned about React in general, what it is and why you could consider using it for building user interfaces. You also learned how to create React projects with the help of npx create-react-app.

In this chapter, you will learn about one of the most important React concepts and building blocks: React as above, components. You will learn that components are reusable building blocks which are used to build user interfaces. In addition, JSX code will be discussed in greater detail so that you will be able to use the concept of components and JSX to build your own, first, basic React apps.
