Node.js is a software system designed for writing highly scalable Internet applications, notably web servers. Programs are written in JavaScript, using event-driven, asynchronous I/O to minimize overhead and maximize scalability. Unlike most JavaScript programs, it is not executed in a web browser, but is instead a server-side JavaScript application.

Node.js consists of Google’s V8 JavaScript engine plus several built-in libraries.
