< 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 >
