We already know that JavaScript is a client-side programming language that can run in the user’s browser. Now, going by this definition, we can describe Node.js as an interface that can be used to run JavaScript on the server itself. Basically, when you run another programming language (say, PHP) on your average server (say, Apache or nGinX), each new connection to the server is created in a new thread. As such, as the number of concurrent users rises, the load on the server rises too, and the only direct way to accommodate more users is to employ a better server, as and when the need arises. Ever had that feeling that you jumped the ship too late, and ended up trying to catch up with the rest of the world? Node.js is currently lining up to be the next big thing, and as support for it increases, so will the number of apps and websites that use it. If you’re looking to extend your web development skillset, you should consider giving Node.js a try! This is one programming script that has everyone talking, and your skills with Node.js will surely not go unnoticed.
