Write a simple javascript program using express and node.js to create a simple webpage that can lead to other pages within the program. if possible, Comment everything out so I could understand how every things works.  But basically, server should be hosted on localhost:8000 and should have a simple starting page. Maybe a welcome message, with at least two "links" that goes to a "homepage" and then a "exit" page.

Answer 1) Below is the javascript program using express and node.js. Below is app.js

// importing the express module

const express = require("express");

const app = express();

// when request is send to home page this returns the home.html

// That is when we type http://localhost:3000/ in URL of browser

app.get("/", function (req, res) {

  res.sendFile(__dirname + "/home.html");

});

// When request to contact page that is http://localhost:3000/contact in the URL

app.get("/contact", function (req, res) {

  res.sendFile(__dirname + "/contact.html");

});

// When request to about page that is http://localhost:3000/about in the URL

app.get("/about", function (req, res) {

  res.sendFile(__dirname + "/about.html");

});

// listen for request.

app.listen(3000, function () {

  console.log("server started at port 3000");

});
