Answer 1

Create the file hello.js in the root directory of your project, and fill it with the following code:

var http = require("http");

http.createServer(function(request, response) {
  response.writeHead(200, {"Content-Type": "text/plain"});
  response.write("Hello World");
  response.end();
}).listen(8888);

First, execute your script with Node.js in the command prompt:

node hello.js

open your browser and point it at http://localhost:8888/ . You will see a message "Hello World" .
