Node.js is an innovative, event-driven input/output system intended for Internet sites which support real-time communication. A few examples of such websites would be web-based browser game portals, web-based chat rooms or hotel reservation portals. The platform handles the info transmitted between the site and its visitors in small bits, which enhances the speed and the overall performance of the site considerably. If some form with three boxes is expected to be filled by a user, for instance, normally all three boxes should be filled and the entire content is then delivered as one large hunk of information to the server. With Node.js, the first box’s content is processed the moment it is inserted, before the user types anything in the second box. Thus, a lot more info can be handled a lot faster and more effectively compared with any conventional platform, which can have a tremendous impact on the site’s overall performance. Node.js is already being employed by some of the top IT firms like Yahoo and Microsoft.
