Node.js is an open-source, event-driven environment built with Google's V8 JavaScript Engine. It is used for scalable web apps that require live communication between a server and the worldwide web users and can noticeably boost the performance of any website that uses it. Node.js is designed to handle HTTP web requests and responses and ceaselessly supplies small bits of info. For instance, in case a new user fills out a registration form, the moment any information is inserted in one of the boxes, it is delivered to the server even if the remaining boxes are not filled out and the user hasn’t clicked any button, so the information is processed much faster. In comparison, conventional platforms wait for the whole form to be filled and one giant hunk of information is then forwarded to the server. No matter how little the difference in the information processing speed may be, circumstances change in case the Internet site expands and there are plenty of persons using it simultaneously. Node.js can be used by booking websites, interactive browser-based video games or online chat applications, for instance, and a lot of companies, including eBay, LinkedIn and Yahoo, have already incorporated it into their services.
