<p>Node.js is a platform built on <a
href="http://code.google.com/p/v8/">Chrome's JavaScript runtime</a>
for easily building fast, scalable network applications. Node.js
uses an event-driven, non-blocking I/O model that makes it
lightweight and efficient, perfect for data-intensive real-time
applications that run across distributed devices.</p>

Node showed us huge performance gains.

<h2>An example: Webserver</h2>
<p>This simple web server written in Node responds with "Hello World" for every request.</p>
<pre>
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(1337, "127.0.0.1");
console.log('Server running at http://127.0.0.1:1337/');</pre>
<p>To run the server, put the code into a file <code>example.js</code> and execute it with the <code>node</code> program:</p>
<pre class="sh_none">
% node example.js
Server running at http://127.0.0.1:1337/</pre>
<p>Here is an example of a simple TCP server which listens on port 1337 and echoes whatever you send it:</p>
<pre>
var net = require('net');
var server = net.createServer(function (socket) {
socket.write("Echo server\r\n");
socket.pipe(socket);
});
server.listen(1337, "127.0.0.1");</pre>
