Steps to create the first "Hello Work" Application

1. Install Node JS on your system (https://nodejs.org/en/download/)
2. Open terminal or command prompt
3. Run command "npm init"
4. Complete all the steps
5. Create the index.js file and copy and paste sample

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/html'});
  res.end('Hello World!');
}).listen(5000);

Start your web browser, and type in the address: http://localhost:5000

You can see the result and render the page with string "Hello world!"
