Node.js is an event-driven environment, which uses Google's V8 JavaScript Engine. It’s used for scalable web apps that require real-time communication between a server and the worldwide web users and can substantially speed up the overall performance of any site that uses it. Node.js is intended to handle HTTP web requests and responses and incessantly provides small bits of info. For instance, if a new user fills out a subscription form, the second any information is entered in any of the boxes, it’s sent to the server even if the rest of the fields are not filled out and the user has not clicked any button, so the information is handled much faster. In comparison, conventional platforms wait for the entire form to be filled out and one huge chunk of information is then forwarded to the server. Regardless of how little the difference in the information processing speed may be, circumstances change if the website grows bigger and there’re many people using it at the same time. Node.js can be used by booking portals, interactive browser-based games or live chat programs, for instance, and numerous companies, including LinkedIn, Yahoo and eBay, have already integrated it into their services.
