What  is  Node.JS? • Node.js is a software platform for scalable server- side and networking applications. • Node.js internally uses the Google V8 JavaScript engine to execute code, and a large percentage of the modules are written in JavaScript. • Node.js contains a built-in asynchronous i/o library for file, socket and HTTP communication. The HTTP and socket support allows Node.js to act as a web server without additional web server software such as Apache.
