// EXPRESS
// This sets up the basic properties for our express server


// Tells node that we are creating an "express" server
const app = express();

// Sets an initial port. We"ll use this later in our listener

let PORT = process.env.PORT || 3000;

// Sets up the Express app to handle data parsing

// ROUTER
// The below points server to a series of "route" files.
// These routes give our server a "map" of how to respond when users visit or request data from various URLs.

// LISTENER
// The below code effectively "starts" the server
