Node.js® is a JavaScript runtime built on Chromes V8 JavaScript engine. As an asynchronous event-driven JavaScript runtime, Nodejs is designed to build 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.

Node.js is an open source, cross-platform runtime environment for developing server-side and networking applications. Node.js applications are written in JavaScript, and can be run within the Node.js runtime on Linux.

Over 6,000 open source packages on NPM. The Node community has many open source projects available to help you save time. These libraries range from simple helpers and charts to full blown frameworks. The idea of NPM modules is quite similar to that of Ruby Gems: a set of publicly available, reusable components, available through easy installation via an online repository, with version and dependency management.
