Routing is how Express decides what code should handle an incoming request. You can create routes for different HTTP methods such as GET, POST, PUT, and DELETE, and use URL parameters, query parameters, and request bodies to work with the data sent by the client.

As an application grows, putting every route in one file quickly becomes difficult to manage. Express routers let you split routes into smaller modules and organize them around features such as users, products, authentication, or orders.
