Node.js is a leading-edge, open-source, event-driven, asynchronous input/output system used for websites which offer live interaction. Several examples of such websites are online browser video game portals, online chat rooms or hotel booking portals. Node.js handles the info sent between the website and its users in little bits, which enhances the load speed and the overall performance of the site tremendously. If a certain form with three boxes has to be filled out by a specific user, for instance, usually all three boxes should be filled and their entire content is then delivered as one sizeable hunk of information to the server. With Node.js, the first box’s content is processed the moment it is inserted, before the user writes anything in the second one. Thus, a lot more info can be handled much faster and more effectively in contrast with any conventional platform, which can have a tremendous influence on the overall performance of the website. Node.js is already being used by some of the biggest IT companies like Microsoft and Yahoo.
