The answer side doesn't link to the question.

Everything works perfectly but when I go to the answer link http://localhost:3000/cards/3?side=answer it doesn't give me a link redirecting me to the question.

cards.js

const express = require('express'); const router = express.Router(); const { data } = require('../data/flashcardData.json'); const { cards } = data;

router.get( '/', ( req, res ) => { const numberOfCards = cards.length; const flashcardId = Math.floor( Math.random() * numberOfCards ); res.redirect( /cards/${flashcardId} ) });

router.get('/:id', (req, res) => { const { side } = req.query; const { id } = req.params;

if ( !side ) {
    return res.redirect(`/cards/${id}?side=question`);
}
const name = req.cookies.username;
const text = cards[id][side];
const { hint } = cards[id];

const templateData = { id, text, name };

if ( side === 'question' ) {
    templateData.hint = hint;
    templateData.sideToShow = 'answer';
    templateData.sideToShowDisplay = 'Answer';      
} else if ( side === 'answer' ) {
    templateData.sideToShow = 'question';
    templateData.sideToShowDisplay = 'Question';
}

res.render('card', templateData);

});

module.exports = router;

card.pug

extends layout.pug

block content section#content h2= text if hint p i Hint: #{hint} a(href=${id}?side=${sideToShow})= sideToShowDisplay br a(href='/cards') Next card
