Node.js is an event-driven platform built with Google's V8 JavaScript Engine. It’s used for scalable apps that require live interaction between a web server and the worldwide web users and can noticeably improve the overall performance of any site that’s using it. Node.js is designed to process HTTP web requests and responses and ceaselessly delivers little bits of information. For example, in case a new user fills a registration form, as soon as any information is inserted in any of the fields, it is forwarded to the server even if the other fields are not filled out and the user hasn’t clicked any button, so the information is handled a lot faster. In comparison, traditional platforms wait for the entire form to be filled out and one giant hunk of information is then forwarded to the server. Irrespective of how tiny the difference in the processing time may be, circumstances change if the site expands and there’re plenty of individuals using it at the same time. Node.js can be used for booking sites, real-time web browser games or instant messaging programs, for example, and plenty of corporations, among them Yahoo, eBay and LinkedIn, have already incorporated it into their services.
