How does prompt variable in CARD.PUG know were the variable resides?

Hello

I dont understand Andrews (author) explaination of how the prompt variable in the pug template card.pug finds its variable.

https://expressjs.com/en/4x/api.html#res.render Documentation says: "The view argument is a string that is the file path of the view file to render."

app.get('/cards', (req, res) => { // creates url /CARDS
    res.render('card', {prompt: "what the"}); // what does CARD mean here? 
})

i think i get it...

app.get('/cards', (req, res) => { // creates url /CARDS
    res.render('card', {prompt: "what the"}); // uses the pug file card and bridges app.js prompt with its call in the pug template
})
