-This code sets up a basic Node.js server using Express framework. It includes the necessary imports, middleware setup, MongoDB connection, and a simple route for the root URL ("/"). The server listens on the specified port (default is 3000) and logs a message when it starts running.
-
-Please note that you may need to modify the MongoDB connection URL (`mongodb://localhost/mydatabase`) based on your specific MongoDB setup.
