Now that you’ve familiarized yourself with the basics of how to work with React, let’s kick things up a few notches. What we are going to do is use React to build a simple, single-page app (also referred to as SPA by the cool kids—and people living in Scandinavia). As we talked about in Chapter 1 forever ago, single-page apps are different from the more traditional multi-page apps that you see everywhere. The biggest difference is that navigating a single-page app doesn’t involve going to an entirely new page. Instead, your pages (commonly known as views in this context) typically load inline within the same page as illustrated in Figure 13-1.
