Node.js is a leading-edge, open-source, event-driven, non-blocking input/output system devised for Internet sites that support real-time interaction. Several instances of such sites would be online browser video game portals, web-based chat rooms or accommodation booking portals. The platform handles the info transmitted between the site and its visitors in little bits, which improves the load speed and the performance of the website considerably. If a given form with 3 boxes should be filled by a specific user, for instance, usually all three boxes should be filled and their entire content is then forwarded as one large chunk of information to the web server. With Node.js, the content in the first box is processed the second it is inserted, before the user types anything in the second box. Thus, much more information can be processed much faster and more efficiently in comparison with any other platform, which can have a considerable impact on the performance of the site. Node.js is already being employed by some of the leading IT companies like Yahoo and Microsoft.
