Express.js: Basic Request Routing
Express routing connects a request's path and HTTP method (like GET `/`) to a specific handler function. This is the core of any Express app, used to define API endpoints or handle form submissions. A common mistake is using the wrong method for a request.
Think of Express routing as a switchboard connecting an incoming request's path and HTTP method (e.g., a GET to `/users`) to a specific handler function. This is the fundamental building block for any Express web server, used to define API endpoints, handle form submissions with POST, or update data with PUT. A common beginner mistake is mismatching the HTTP method. If a client sends a POST request but you only defined `app.get`, Express won't find the route and will return a 404 error.
