1 React is evolving
This chapter will give a brief overview of React and its new features, to whet your appetite for the details that follow later in the book.
1.1 What is React?
Say you are creating a user interface for the web, the desktop, for a smartphone, or even for a VR experience. You want your page or app to display a variety of data that changes over time, like authenticated user info, filterable product lists, data visualization or customer details. You expect the user to interact with the app, choosing filters and data sets and customers to view, filling in form fields, or even exploring a VR space! Or maybe your app will consume data from a network or from the Internet, like social media updates, stock tickers, or product availability. React is here to help.
