Node.js — Run JavaScript Everywhere

Node.js® is a JavaScript runtime built on Chrome's V8 JavaScript engine.

Node.js is an open-source, cross-platform, back-end JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside a web browser. Node.js lets developers use JavaScript to write command line tools and for server-side scripting—running scripts server-side to produce dynamic web page content before the page is sent to the user's web browser. Consequently, Node.js represents a 'JavaScript everywhere' paradigm, unifying web application development around a single programming language, rather than different languages for server-side and client-side scripts.

Key Features of the Site

Asynchronous and Event Driven

All APIs of Node.js library are asynchronous, that is, non-blocking. It essentially means a Node.js based server never waits for an API to return data.

Very Fast

Being built on Google Chrome's V8 JavaScript Engine, Node.js library is very fast in code execution.

Single Threaded but Highly Scalable

Node.js uses a single threaded model with event looping. Event mechanism helps the server to respond in a non-blocking way and makes the server highly scalable as opposed to traditional servers which create limited threads to handle requests.

No Buffering

Node.js applications never buffer any data. These applications simply output the data in chunks.

License

Node.js is released under the MIT license.
