In this chapter, we started to create React components and explored their basic features. In particular, we:

• Learned how to define a component as a class derived from React.Component, and how to import specific CSS styles
• Explored the syntax of JSX, which allows us to quickly define the graphical aspect of a component and use React components that were defined elsewhere
• Combined React components in order to build other components
• Used state management features so that React components automatically update their visual representation when data changes

In the next chapter, we will analyze how to manage user interaction with a React-based application; in other words, how to capture events and make a UI react to those events.
