Node.js is an open-source, event-driven environment built with Google's V8 JavaScript Engine. It is used by scalable applications that need live interaction between a web server and the worldwide web users and can significantly boost the overall performance of any site that uses it. Node.js is designed to process HTTP web requests and responses and constantly supplies little amounts of info. For instance, in case a new user fills in a registration form, the second any info is entered in one of the boxes, it is delivered to the server even if the remaining fields are not filled and the user hasn’t clicked on any button, so the information is processed a whole lot faster. In comparison, 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 information processing speed may be, circumstances change when the site expands and there are plenty of individuals using it simultaneously. Node.js can be used by booking portals, real-time web browser games or live chat platforms, for instance, and a lot of corporations, among them Yahoo, eBay and LinkedIn, have already included it in their services.
