Node.js is an advanced event-driven platform, which is used to create scalable web apps. It uses the Google V8 JavaScript engine and it handles HTTP requests and responses between a web server and a large number of users much more efficiently than any traditional system. What makes Node.js unique is the fact that in difference between conventional platforms which handle the info in sizeable chunks, it processes everything in little bits. For instance, when a user has to fill out a couple of fields on a site, Node.js processes the information from the first field the moment it’s inserted, utilizing the server’s processing capabilities more efficiently. In contrast, conventional platforms wait for all the fields to be filled out and while the information in them is being processed, requests from other users remain in the queue. The difference may be negligible for a single person, but it surely does make a difference if a huge number of people are browsing a website at the same time. Several examples of sites where Node.js can be used are dining reservation portals, live chat rooms or interactive browser video game portals, in other words websites that offer fast live interaction.
