Node.js is an avant-garde, open-source, event-driven, asynchronous input/output system intended for websites that offer real-time interaction. A few examples of such websites would be web-based browser game portals, live chat rooms or accommodation reservation portals. Node.js processes the info transmitted between the website and its users in small bits, which boosts the load speed and the performance of the website noticeably. If a certain form with three boxes is expected to be filled by a particular user, for example, ordinarily all three boxes should be filled out and the entire content is then sent as one big hunk 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 types anything in the second box. Thus, much more information can be handled much faster and more efficiently compared to any other platform, which can have an enormous impact on the site’s overall performance. Node.js is already being employed by many of the biggest IT firms such as Yahoo and Microsoft.
