JavaScript Express Basics Parameters, Query Strings, and Modularizing Routes Modular Routes

In the Cards.js file, why leave out the /cards when setting the route?

cards.js 
const express = require('express');
const router = express.Router()

router.get('/', (req, res) => {
  res.render('card', {prompt: "Who is buried in Grant's Tomb?", hint: "Think about whose tomb it is."})
});

module.exports = router;

I don't understamd the part where he says that we don't have to put the '/cards' route, only '/'.

I tried leaving it unchanged and it thew an error, and when I corrected it back to what he said, it worked fine. The problem is that it doesn;t make sense to me to leave only the root route, and not the one w need.

Thanks anyone for any help :D

because in app.js you already have the route 

app.use('/cards', cardsRoute);

where cardsRoute is the path to the file.

const cardsRoute = require('./routes/cards');

if have the same name in the cards.js file. It should work. I dint remove mine and it works fine.

router.get('/cards', (req, res) => {

    res.render('card', { prompt: "Who is buried in Grant;s tomb?", hint: "Think about whose tomb" });
});

I am not sure what is the best practice on that.

If I remember rightly it's because there's another file somewhere that makes it so cards routes have their own base route called /"cards". This would be so that each card can be uniquely identified with a url variable. "cards/1/" for example.

You're right. I saw it later in the next videos that /route was going to become, so to say, a 'root route' for the cards numbers. I just needed to be patient :P

Thanks Jonathan!
