Node.js is a leading-edge, event-driven asynchronous input/output platform devised for sites which support interactive communication. Several examples of such websites would be online browser game portals, online chat rooms or hotel booking portals. The platform processes the info sent between the website and its users in small bits, which accelerates the load speed and the overall performance of the site substantially. If some form with three boxes should be filled out by a particular user, for example, ordinarily all three boxes should be filled out and their entire content is then submitted as one giant chunk of information to the server. With Node.js, the first box’s content is processed the second it is inserted, before the user writes anything in the second one. Thus, a lot more information can be handled much faster and more efficiently in comparison to any conventional system, which can have a remarkable influence on the overall performance of the site. Node.js is already being employed by some of the top IT firms such as Microsoft and Yahoo.
