Node.js is an advanced event-driven platform, which is used to set up scalable web applications. It is built with Google's V8 JavaScript Engine and it processes HTTP requests and responses between a server and an enormous number of users more effectively than any other system. What makes Node.js exceptional is the fact that in difference between conventional systems that handle the info in large hunks, it processes everything in little bits. For example, when a user needs to fill out a few fields on a site, Node.js handles the information from the first field once it is typed, utilizing the server’s processing capabilities more effectively. In contrast, other systems 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 insignificant for a single person, but it certainly does make a difference when a huge number of people are navigating a site at the very same time. A few instances of Internet sites where Node.js can be employed are dining reservation portals, online chat rooms or interactive browser video game portals, in other words sites that support fast live communication.
