Creating an Express Server

Definition

Creating an Express server involves importing the `express` module, initializing an `app` object, defining at least one route, and telling the app to `listen` on a specific network port. The `app.listen()` function binds and listens for connections on the specified host and port. It is essentially a wrapper around Node's core `http.Server.listen()` method.
