Answer
Routing determines what happens when a specific URL and HTTP method are accessed.
Quick Answer
Routing maps incoming HTTP requests (URL + method) to handler functions. In Express: app.get('/users', handler) handles GET requests to /users; app.post('/users', handler) handles POST. Routes let you organize your API into clean, meaningful endpoints. Express Router lets you group related routes into separate files.
