Using the Express framework, which of the following is the correct syntax for defining a resource path with a route parameter named `id` ? code example

Example 1: express hello world

//to run : node filename.js
const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => res.send('Hello World!'))

app.listen(port, () => console.log(`Example app listening at http://localhost:${port}`))

//visit localhost:3000
// assuming you have done 1) npm init 2) npm install express

Example 2: express route parameters

app.get('/',function(req,res)
{
    res.send("Route path at base address");
});
