In this chapter, we created a mobile app using NativeScript. We used a plugin to scan QR codes. The scans are saved, so the list is persisted after a restart of the app. Finally, we added custom styles to our app.
In the next chapter, we will build a spreadsheet web app using React. We will discover some principles of functional programming and learn how we can handle the state of an application. We will also see how we can build a cross-platform application.
