Node JS

Description

NodeJS is an open supply framework that has been developed for developers to know and build web applications with the assistance of JavaScript. NodeJS uses an event-driven, non-blocking IO model and server-side JavaScript atmosphere. NodeJS is mainly centered on several important ideas in it like file system working, streams, buffers and building communications protocol(http) server with NodeJS.
