Node.js is an open-source, event-driven runtime environment built with the Google V8 JavaScript engine. It’s used for scalable applications that need real-time communication between a web server and the online users and can tremendously accelerate the overall performance of any Internet site that’s using it. Node.js is intended to handle HTTP web requests and responses and ceaselessly supplies small amounts of info. For example, in case a new user fills a subscription form, as soon as any info is inserted in any of the boxes, it’s delivered to the server even if the rest of the fields are not filled and the user has not clicked any button, so the information is handled much faster. In comparison, conventional platforms wait for the whole form to be filled out and one huge hunk of information is then sent to the server. No matter how little the difference in the information processing time may be, things change if the site expands and there are lots of people using it simultaneously. Node.js can be used by online booking portals, interactive browser-based video games or online chat software, for example, and many corporations, among them LinkedIn, eBay and Yahoo, have already implemented it in their services.
