title: Node.js Asynchronous JavaScript Framework
tags: ["Development", "JavaScript", "Node.js"]
---
<p class="excerpt">
Node.js is an evented I/O framework for the V8 JavaScript engine. It is intended for writing scalable network programs such as web servers.
</p>
<p>
Node.js is similar in purpose to Twisted for Python, Perl Object Environment for Perl, and EventMachine for Ruby. Unlike most JavaScript, it is not executed in a web browser, but it is rather related to server-side JavaScript. Node.js implements some CommonJS specifications[1]. Node.js includes a REPL environment for interactive testing.
</p>
<pre>
var sys = require('sys'),
http = require('http');
http.createServer(function (request, response) {
response.writeHead(200, {'Content-Type': 'text/plain'});
response.end('Hello World\n');
}).listen(8000);
sys.puts('Server running at http://127.0.0.1:8000/');
</pre>
