Node.js is an open-source, event-driven runtime system built with the Google V8 JavaScript engine. It’s used by scalable apps that require live interaction between a web server and the online users and can significantly boost the performance of any website that’s using it. Node.js is designed to handle HTTP web requests and responses and ceaselessly supplies little amounts of info. For instance, in case a new user fills in a signup form, the moment any information is entered in one of the fields, it’s forwarded to the server even if the remaining fields are not filled and the user has not clicked on any button, so the information is handled a lot faster. In contrast, conventional platforms wait for the whole form to be filled and one large hunk of information is then sent to the server. Irrespective of how tiny the difference in the information processing time may be, circumstances change in case the Internet site expands and there’re numerous users using it at the same time. Node.js can be used by booking websites, interactive browser-based games or instant messaging clients, for instance, and lots of corporations, including Yahoo, LinkedIn and eBay, have already integrated it into their services.
