Node.js is a cutting-edge event-driven platform, which is used to create scalable applications. It uses Google's V8 JavaScript Engine and it handles requests and responses between a web server and an immense number of online users much more efficiently than any conventional system. What makes Node.js exceptional is the fact that in difference between conventional systems which process the info in huge hunks, it handles everything in little bits. As an illustration, when a user needs to fill in a few fields on an Internet site, Node.js processes the info in the first field the moment it is inserted, utilizing the server’s processing resources more effectively. In contrast, conventional platforms wait for all the fields to be filled and while the information from them is being processed, requests from other users stay in the queue. The difference may be negligible for a single person, but it indeed does make a difference when a huge number of individuals are navigating a site at once. Several examples of sites where Node.js can be employed are online dinner booking portals, chat rooms or interactive browser game portals, in other words websites that need fast live interaction.
