Node.js is an open-source, event-driven system, which uses the Google V8 JavaScript engine. It is used by scalable web apps that require live interaction between a web server and the worldwide web users and can noticeably boost the overall performance of any Internet site that uses it. Node.js is intended to process HTTP web requests and responses and ceaselessly supplies tiny bits of information. For instance, if a new user fills out a signup form, once any information is inserted in one of the fields, it is forwarded to the server even if the other boxes are not filled out and the user has not clicked on any button, so the info is processed a whole lot faster. In comparison, conventional systems wait for the whole form to be filled and one huge hunk of information is then forwarded to the server. Irrespective of how small the difference in the processing speed may be, circumstances change in case the website grows bigger and there are many individuals using it simultaneously. Node.js can be used by booking websites, interactive browser video games or online chat applications, for instance, and plenty of corporations, including Yahoo, eBay and LinkedIn, have already integrated it into their services.
