Node.js is a leading-edge, event-driven asynchronous I/O system devised for Internet sites which offer real-time communication. Several instances of such sites would be online browser game portals, live chat rooms or hotel reservation portals. The platform processes the info transmitted between the site and its visitors in small bits, which enhances the speed and the overall performance of the website considerably. When a certain form with three boxes should be filled by a user, for example, usually all three boxes should be filled and the whole content is then forwarded as one big chunk of information to the web server. With Node.js, the first box’s content is processed as soon as it is entered, before the user writes anything in the second one. In this way, a lot more info can be handled a lot faster and more effectively in contrast with any other system, which can have a remarkable impact on the overall performance of the website. Node.js is already being employed by many of the top IT firms like Microsoft and Yahoo.
