Name Variable

In this video when Andrew assigns the name variable to the cookie:

"const name = req.cookies.username";

"res.render('index', { name });"

I am guessing this extra code is completely optional?? and that:

"res.render('index', { name: req.cookies.username });"

Is still acceptable?? for me the original method is much easier to understand...

You're right they're interchangeable, meaning you can either create a variable and assign it to req.cookies.username or just put req.cookies.username straight into the render. However by creating a variable and assigning it first, this allows for more flexibility with your code (i.e. you can redefine the name variable to something else if needs be, or reuse the variable without having to type req.cookies.username over and over again) but also this allows better readability for other developers or yourself at a later stage.
