Node.js is an open-source, event-driven runtime system, which uses the Google V8 JavaScript engine. It’s used for scalable applications that need live communication between a web server and the Internet users and can substantially boost the overall performance of any website that’s using it. Node.js is intended to process HTTP web requests and responses and ceaselessly supplies little bits of info. For example, if a new user fills out a subscription form, the moment any info is inserted in any of the fields, it’s submitted to the server even if the remaining fields are not filled out and the user has not clicked any button, so the information is processed a whole lot faster. In comparison, conventional platforms wait for the whole form to be filled and one large chunk of information is then submitted to the server. Regardless of how small the difference in the processing time may be, circumstances change when the Internet site grows bigger and there are a lot of users using it simultaneously. Node.js can be used for online reservation portals, real-time browser-based games or live chat systems, for example, and many corporations, including Yahoo, eBay and LinkedIn, have already integrated it into their services.
