But if you have any experience with Node Express servers, you know this is fairly simple syntax. The app is the main object holding all the methods Koa offers, such as listen, and use. And one really cool areas of Koa is you can spin up multiple servers if you'd like, not just one. So you could run an https server on one port, and one on another port. So for example, in this code here we're seeing the http server running on port 3000, and then the https server running on port 3001. So use, like Express, is the main syntax we'll use to add any functions, or do anything with their server. And you'll see it repeated multiple times as we explore other areas of Koa. So when you want to create anything or any functions the server may do, you'll start with the app.use like so, and then the function.
