Does the server send the cookie from the server to browser? Why can't we use req.cookie() as the cookie is saved when the client is sending the request to the server?

Take this code snippet for example:
app.post('/hello', (req, res) => { res.cookie('username', req.body.username); //set cookie on client to input on username res.redirect('/'); });
When the server we set up receives a POST request, we have programmed the server to respond with res.cookie to set a cookie on the client called username.
As the server we are responding, so we want to use the Response object and its methods.
Hope this helps!
