Node.js is an open-source, event-driven system, which uses Google's V8 JavaScript Engine. It is used by scalable web apps that need real-time communication between a web server and the online users and can tremendously accelerate the performance of any website that uses it. Node.js is designed to process HTTP requests and responses and incessantly supplies little amounts of info. For example, in case a new user fills a registration form, the moment any information is inserted in any of the boxes, it is delivered to the server even if the other fields are not filled out and the user has not clicked on any button, so the info is handled a lot faster. In contrast, traditional platforms wait for the whole form to be filled and one big chunk of information is then delivered to the server. Irrespective of how tiny the difference in the processing time may be, circumstances change in case the site grows bigger and there’re numerous persons using it at the same time. Node.js can be used by booking portals, interactive web browser-based video games or instant messaging software, for instance, and lots of corporations, among them LinkedIn, eBay and Yahoo, have already included it in their services.
