There has been so many killer programming libraries released over the past five years it is hard to keep up with and have a chance to play with. I have very been impressed by node.js. What a genius idea and execution. Bravo

An example of a web server written in Node which responds with “Hello World” for every request.
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(8124, "127.0.0.1");
console.log('Server running at http://127.0.0.1:8124/');
