Routing & Middleware in Express

Welcome back! In this lesson, we'll dive into routing and middleware in Express. These are core concepts for building powerful and organized web applications.

Routing helps your server understand what to do when it receives different requests, like showing a user profile or saving new data.

A route tells your Express app how to respond to a specific type of request to a particular URL path. You define routes using methods like app.get(), app.post(), app.put(), and app.delete().

Each route method takes a path and a handler function that executes when the route is matched.
