Node.js is an innovative event-driven system, which is used to develop scalable Internet apps. It’s built with the Google V8 JavaScript engine and it handles HTTP requests and responses between a server and an immense number of online users more effectively than any traditional platform. What makes Node.js special is the fact that in contrast to conventional platforms that handle the info in massive hunks, it processes everything in tiny bits. For example, when a user has to fill a few fields on a website, Node.js processes the info in the first field the second it is entered, utilizing the server’s processing capabilities more effectively. In contrast, conventional systems wait for all the fields to be filled and while the information in them is being processed, requests from other users stay in the queue. The difference may be negligible for a single person, but it surely does make a difference if a huge number of users are browsing a website all at once. Several examples of websites where Node.js can be used are dinner booking portals, web-based chat rooms or interactive browser game portals, in other words websites that need fast real-time communication.
