The rise in popularity of JavaScript has brought a lot in web development. What can be done on the web with JavaScript running on the server, as well as in the browser, was hard to imagine just several years ago. Node.js is a packaged compilation of Google’s V8 JavaScript engine, the library platform abstraction layer, and a core library, which is itself primarily written in JavaScript.  Node.js is a packaged compilation of Google’s V8 JavaScript engine, the library platform abstraction layer, and a core library, which is itself primarily written in JavaScript.” Beyond that, it’s worth noting that Ryan Dahl, the creator of Node.js, was aiming to create real-time websites with push capability, “inspired by applications like Gmail”. In Node.js, he gave developers a tool for working in the non-blocking, event-driven I/O paradigm. After over 20 years of stateless-web based on the stateless request-response paradigm, we finally have web applications with real-time, two-way connections.
