Our simple Hello World application and Hello World examples are looking great and working exactly as they should; so, let's review what we've learned in this chapter.
To begin with, we covered React and Firebase and how easy it is to set up the Firebase account and configuration. We also looked at the difference between Realtime Database and Firestore. Apart from that, we learned how simple it is to initialize Realtime Firebase Database with JavaScript and started building our first Hello World application. The Hello World application that we created demonstrates some of Firebase's basic features, such as the following:
- About Realtime Database and Firestore
- Difference between Realtime Database and Firestore
- Firebase account creation and configuration with JavaScript App
- Firebase Events (value and child_data)
- Saving the values into the database
- Read the values from the database
In Chapter 2, Integrate React App with Firebase, let's build a React application with Firebase. We will explore some more React and Firebase fundamentals and introduce the project that we will build over the course of this book.
