Questions

Fоr the next three (3) questiоns, аssume the bоdy of the index.ejs file contаins only the code shown below     Welcome to Our Pаge            Item 1              Item 2              Item 3      with the referenced item.ejs file containing   and that the server.js file has all the required packages, templating engines, paths, and file references set correctly, leaving just the “root” and “item” routes as shown below. You can assume that server.js is run on the localhost:port, where the port number is given and not relevant for the questions. app.get('/', (req, res) => {  res.render('index', {    itemName: null  });});app.get('/item/:itemID', (req, res) => {  const prdID = parseInt(req.params.itemID);  const curItem = itemData.find(item => item.itemID === prdID);  if (curItem) {    const prdName = curItem.itemName;    const prdPrice = curItem.itemPrice;    const prdImage = curItem.itemImage;    res.render('index', {      itemID: prdID,      itemName: prdName,      itemPrice: prdPrice,      itemImage: prdImage    });  } else {    res.status(404).send('Item not found');  }}); Finally, you can assume that the itemData is coming from the following items.json file: [ {"itemID": 1, "itemName": "Item1", "itemPrice": "$11.99", "itemImage": "/images/item1.png"},  {"itemID": 2, "itemName": "Item2", "itemPrice": "$19.99", "itemImage": "/images/item2.png"},  {"itemID": 3, "itemName": "Item3", "itemPrice": "$9.99", "itemImage": "/images/item3.png"} ]
