Google has made more contributions in evolving, developing, and utilizing of JavaScript than any other organization. It was Google that introduced the V8 engine in its flagship web browser, Chrome. V8 is the backbone engine of the browser, and due to the smart usage of JavaScript, the browser is faster, robust, and adaptable to web and Android devices.

In the year 2009, Node.js arrived based on the same V8 engine as in Chrome. This is the server side of JavaScript, but far more better and advanced than what Netscape had introduced in late 90s. The whole idea of Node.js is to develop nonblocking input/output (I/O) and with few lines of codes, the server can serve up to 20K clients at a given slot of time.

Soon after Node.js, an entire stack of development has been introduced by the name of MEAN stack, which is an acronym of MongoDB, Express.js, Angular.js, and Node.js; where MongoDB is document based, NoSQL is a JavaScript-based database, Express.js is for a presentation layer, Angular.js is for frontend development of an app, and Node.js as the server that runs the entire show.
