Hello node. JS!

Write a small program such as hello_node.js to verify whether the installation is correct:

1 var http =require('http');
2 http.createServer(function(req, res){
3   res.writeHead(200,{'Content-Type':'text/plain'});
4   res.end('Hello Node.js\n');}).listen(8124,"127.0.0.1");
5 console.log('Server running at http://127.0.0.1:8124/');

Use node to run this code

1 node hello_node.js
2 Server running at http://127.0.0.1:8124/

Now, open http: // 127.0.0.1: 8124/in a browser, and you should be able to see good news.
