Creating Your First Express Server
Think of an Express app as three steps: require the library, create an instance, and listen on a port. This is the foundation for any Express-based API or web server.
An Express app is a Node.js script that requires the library, creates an application instance with `express()`, and starts a server with `app.listen()`. This `app` object is where you define all your routes and middleware. This pattern is the universal starting point for any Express-based web server or API. The most common footgun is defining routes but forgetting to call `app.listen()`, which causes your script to run and exit without ever starting the server to accept connections.
