4.Click on the file app.js in File Manager to open it in built-in text editor and put the code below:

const http = require('http');

http.createServer(function(request, response) {
response.writeHead(200, {'Content-Type': 'text/plain'});
response.end("Hello, World!\n");
}).listen(process.env.PORT);

console.log('App is running...');
