As an asynchronous event-driven JavaScript runtime, Node.js is designed to build scalable network applications. In the following “hello world” example, many connections can be handled concurrently. Upon each connection, the callback is fired, but if there is no work to be done, Node.js will sleep.

Node.js is an open-source, cross-platform, JavaScript run-time environment that executes JavaScript code outside of a 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. Node.js lets you write JavaScript on both lient and server Node.js holds a lot of relative libraries which we normally use in JavaScript for general purpose programming language.
JavaScript is usually associated with the front-end side, but since Node.js, as a back-end technology, uses it as well, development speed and the productivity of both teams increases significantly. This framework allows companies to spend less on hardware because it can handle the same amount of load with less horsepower.
