Node.js is a leading-edge, event-driven I/O system designed for Internet sites that offer live communication. A few instances of such websites would be online browser-based game portals, live chat rooms or accommodation booking portals. Node.js handles the info exchanged between the site and its users in little bits, which boosts the speed and the overall performance of the website substantially. If a certain form with three boxes should be filled out by a user, for instance, usually all three boxes should be filled and their entire content is then forwarded as one massive hunk of information to the web server. With Node.js, the content in the first box is processed once it is entered, before the user writes anything in the second box. Therefore, a lot more info can be processed much faster and more efficiently as opposed to any other platform, which can have a considerable influence on the website’s overall performance. Node.js is already being employed by some of the leading IT corporations such as Microsoft and Yahoo.
