How does express.Router work?

express.Router() is a class that creates modular, mountable route handlers that can be used to handle requests based on the URL path and HTTP method, allowing developers to organize their routes in a more structured and reusable manner. It provides functions for defining routes for various HTTP methods like GET, POST, PUT, DELETE, and other middleware functions that can be used to process incoming requests or modify outgoing responses. Each router can be mounted on a specific path and can have its own middleware stack, making it possible to create complex applications with multiple routers and middleware functions.

// Import the necessary modules
const express = require("express");

// Create a new router object
const router = express.Router();

// Define a route on the router object
router.get("/", (req, res) => {
  res.send("Hello, World!");
});

// Export the router object for use in the main application
module.exports = router;

In the above example, we create a new router object using express.Router(), define a route using .get(), and then export the router object for use in the main Express application. The router object can then be mounted on a path in the main application using app.use().
