Node.js is an open-source, event-driven runtime environment, which uses Google's V8 JavaScript Engine. It is used by scalable web apps that need real-time interaction between a web server and the Internet users and can substantially boost the performance of any website that uses it. Node.js is intended to process HTTP web requests and responses and incessantly provides tiny amounts of information. For instance, in case a new user fills a signup form, once any info is inserted in any of the boxes, it’s submitted to the server even if the rest of the fields are not filled and the user has not clicked on any button, so the information is handled a lot faster. In comparison, traditional platforms wait for the whole form to be filled and one big hunk of information is then submitted to the server. Regardless of how tiny the difference in the information processing time may be, circumstances change when the site grows bigger and there’re many users using it simultaneously. Node.js can be used for online reservation portals, interactive web browser-based games or online chat systems, for instance, and a lot of companies, among them eBay, LinkedIn and Yahoo, have already integrated it into their services.
