// Import Express.js and EJS
const express = require('express');
const ejs = require('ejs');
// Create an Express.js app
const app = express();
// Use EJS as the view engine
app.set('view engine', 'ejs');
// Set up a route to the home page
app.get('/', function(req, res) {
res.render('home');
});
// Start the server on port 3000
