In this chapter, we started to explore the React world. In particular, we:

• Established that React is a user interface library, used to implement the View part of various MV* design patterns
• Introduced the create-react-app tool, which helps us to set up a development environment to build React-based applications
• Explored the items composing a typical React-based application
• Analyzed the approach to designing user interfaces that best fits in the React world

In the next chapter, we will discover how to create React components to build user interfaces for our application.
