Node.js is an innovative, event-driven I/O system intended for websites that offer real-time communication. Some instances of such websites are web-based browser game portals, web-based chat rooms or hotel reservation portals. The platform handles the info exchanged between the Internet site and its visitors in tiny bits, which accelerates the speed and the performance of the site significantly. If a given form with 3 boxes is expected to be filled out by a particular user, for instance, usually all three boxes should be filled and the entire content is then submitted as one big hunk of information to the server. With Node.js, the first box’s content is processed once it is inserted, before the user types anything in the second one. In this way, much more information can be handled much faster and more effectively compared with any traditional system, which can exert an enormous influence on the website’s performance. Node.js is already being employed by some of the largest IT corporations such as Yahoo and Microsoft.
