Node.js is a cutting-edge event-driven system, which is used to build scalable Internet apps. It’s built with the Google V8 JavaScript engine and it handles HTTP requests and responses between a web server and a huge number of Internet users more effectively than any other system. What makes Node.js exceptional is the fact that unlike traditional systems which process the information in massive hunks, it processes everything in little bits. For example, if a user needs to fill a few fields on a website, Node.js processes the info in the first field the moment it’s entered, utilizing the server processing time more efficiently. In comparison, conventional 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 one single user, but it absolutely does make a difference if an enormous number of individuals are visiting a website simultaneously. A couple of instances of Internet sites where Node.js can be applied are online dinner reservation portals, web-based chat rooms or interactive browser game portals, in other words websites that support fast live interaction.
