JavaScript Express Basics Parameters, Query Strings, and Modularizing Routes Linking Around the Application

Do you need to create a new route to randomize the cards?

I added the following line of code to my conditional:

    templateData.id = Math.floor(Math.random() * cards.length);

and now when someone clicks the Question link, they are given a new random card. This solution is functional but should I do be doing it the way Andrew does in the video?

Here's the whole route:

router.get("/:id", (req, res) => {
  const side = req.query.side;
  const id = req.params.id;
  const text = cards[id][side];
  const hint = cards[id].hint;

  const templateData = { id, text };

  if (side === "question") {
    templateData.hint = hint;
    templateData.sideToShow = "answer";
  } else if (side === "answer") {
    templateData.sideToShow = "question";
    templateData.id = Math.floor(Math.random() * cards.length);

  res.render("card", templateData);
