What do you know about Routing in ExpressJS?

Routing refers to how an application’s endpoints (URIs) respond to client requests. We define routing using methods of the Express app object that correspond to HTTP methods; for example, app.get() to handle GET requests and app.post to handle POST requests. The application “listens” for requests that match the specified route(s) and method(s), and when it detects a match, it calls the specified callback function.
