In this chapter, you learned how to kick-start a React Native project using the Expo command-line tool. First, you learned how to install the Expo tool. Then, you learned how to initialize a new React Native project. Next, you started the Expo development server and learned about the various parts of the development server UI. In particular, you learned how to connect the development server with the Expo app on any devices that you want to test your app on.
Expo also has the Snack service, which lets us experiment with snippets of code or entire Git repositories. You learned how to import a repository and run it on virtual iOS and Android devices. In the next chapter, we'll look at how to build responsive layouts in our React Native apps.
