Node.js is a cutting-edge, event-driven asynchronous input/output system used for sites which offer real-time interaction. Some examples of such sites would be online browser-based video game portals, live chat rooms or accommodation booking portals. Node.js handles the info transmitted between the site and its users in little bits, which improves the loading speed and the performance of the website tremendously. When a given form with three boxes is expected to be filled out by a particular user, for instance, ordinarily all three boxes should be filled and the entire content is then submitted as one giant 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, much more information can be handled a lot faster and more effectively in contrast with any other platform, which can exert a remarkable influence on the website’s overall performance. Node.js is already being used by many of the biggest IT corporations like Yahoo and Microsoft.
