Why do we use {}? As in: res.render('hello', {name: req.body.username)}) Why is req.body.username in brackets?

I'm curious what this syntax means.

app.post('/hello', (req, res) => { res.render('hello', {name: req.body.username}); });

Why is req.body.username in {}?

Hi Kyle,

You wrap it in curly brackets because it has to be an object where the property name is name and the value is the value of req.body.username.

Cheers!

The entire assignment of name to the value of req.body.username is in the brackets, because it is an 'injected code segment', or a function that is executed at that stage. In essence, you are simply asking the program to do this task, when you reach that segment of the code;

'Render hello.pug, and also assign name to the value of req.body.username immediately' is in essence the command you are giving.
