Node.js is an event-driven runtime system built with Google's V8 JavaScript Engine. It is used by scalable apps that require real-time interaction between a web server and the Internet users and can noticeably boost the performance of any website that uses it. Node.js is designed to process HTTP web requests and responses and incessantly supplies little bits of information. For example, in case a new user fills out a registration form, the moment any info is entered in one of the boxes, it is submitted to the server even if the remaining fields are not filled and the user has not clicked any button, so the info is handled a whole lot faster. In contrast, conventional platforms wait for the whole form to be filled and one large chunk of information is then sent to the server. Irrespective of how small the difference in the processing speed may be, circumstances change in case the website expands and there are numerous individuals using it at the same time. Node.js can be used by booking portals, interactive web browser-based video games or online chat apps, for example, and numerous corporations, among them Yahoo, eBay and LinkedIn, have already included it in their services.
