How do I use routes in my web application?

Using routes in a web application allows you to define how different URLs map to specific content or functionality. What framework are you using?

I'm using Express.js for my Node.js application.

Great! In Express.js, you can define routes using the app.get(), app.post(), etc. methods. For example, app.get('/home', (req, res) => { res.send('Welcome to Home!'); }); will respond to GET requests at the '/home' URL.

Can I use parameters in my routes?

Yes, you can! You can define route parameters using a colon. For example, app.get('/user/:id', (req, res) => { res.send(User ID: ${req.params.id}); }); will capture the user ID from the URL.
