Node.js is a cutting-edge event-driven platform, which is used to set up scalable applications. It’s built with Google's V8 JavaScript Engine and it handles requests and responses between a server and a large number of users much more effectively than any conventional platform. What makes Node.js one of a kind is the fact that unlike traditional systems that process the information in massive hunks, it processes everything in small bits. For example, if a user has to fill in several fields on a website, Node.js handles the info from the first field the moment it is inserted, utilizing the server’s processing resources more efficiently. In comparison, other platforms wait for all the fields to be filled out and while the info from them is being processed, requests from other users stay in the queue. The difference may be negligible for a single person, but it undoubtedly does make a difference if an enormous number of individuals are using a website simultaneously. A few examples of sites where Node.js can be employed are online dinner reservation portals, web-based chat rooms or interactive browser-based game portals, in other words websites that offer fast live communication.
