Node.js is an event-driven, server-side JavaScript environment. Node runs JavaScript using the V8 engine developed by Google for use in their Chrome web browser. Leveraging V8 allows Node to provide a server-side runtime environment that compiles and executes JavaScript at lightning speeds. The major speed increase is due to the fact that V8 compiles JavaScript into native machine code, instead of interpreting it or executing it as bytecode. Node is open source, and cross-platform, running on Mac OSX, Windows, and Linux.
But JavaScript? On the server-side? Why? Though JavaScript has traditionally been relegated to menial tasks in the web browser, it’s actually a fully-functional programming language, capable of anything that more traditional languages like C++. Ruby, or Java, are. Furthermore, JavaScript has the advantage of an excellent event model, ideal for asynchronous programming. JavaScript is also a ubiquitous language, well known by millions of developers. This lowers the learning curve of Node.js, since most devs won’t have to learn a new language to start building Node.js apps.(1)
