Node, NodeJs, Node.js

In software development, Node.js is an open source platform using a Javascript engine to execute computer programs written in the programming language Javascript on a server. Node.js, or just Node, has since its first version in 2009 become a popular tool for building web applications. Some of its advantages over traditional server platforms are that Node is designed to create scalable Internet applications, particularly web servers. Programs are written in Javascript to run on the system, and use event-driven, asynchronous I/O to minimize overhead and maximize scalability.
