Web Development stands on the foundation of the building and maintaining cloud-based applications that are used for various purposes, and to develop an application it becomes necessary to employ a standardized stack software. This is where the MEAN comes into the picture, MEAN is the latest trend in full-stack JavaScript development that combines the technologies MongoDB, Express.js, AngularJS, and Node.js.
MEAN works perfectly for JavaScript developers as it enables the entire client-to-server code to be written in JavaScript. The other advantages of MEAN add up to its flexibility and open-source nature, which make it comparatively easy to learn and customize applications to suit one’s needs.
Java has been ruling the roost as the no 1 programming language for many years now. The rough estimates also state that there might be more than 3 billion devices all over the world that run on Java scripts. So, MEAN being a collection of leading Java programming languages eliminates the need to hire different personnel for different parts of the application.
After learning MEAN Stack you are ready for creating end-to-end encryption for cloud-ready applications with ease. The fundamentals of MEAN Stack Development lie in its own web server and database, they can be used much more efficiently to create cloud hosting applications in a cost-effective and productive manner.

The term MEAN stack refers to a collection of JavaScript-based technologies used to develop web applications. MEAN is an acronym for MongoDB, ExpressJS, AngularJS, and Node. js. From client to server to database, MEAN is full-stack JavaScript.
MEAN is also an open-source stack available for developing web applications in an organized manner.
Mastering MEAN Stack will be simpler for you if you know the basics of Javascript. Following are the prerequisites required for learning MEAN Stack are
On the Front
HTML
CSS
JavaScript
On the Back End
Server-side scripting
Database
STEP 1 : Download and install the latest release of Node.JS using all default options.
STEP 2 : Download and install the latest release of MongoDB using ‘’Complete’’ setup type
STEP 3 : Create a MongoDB data directory
STEP 4 : Start MongoDB server by running ‘’mongod.exe’’ from the command line.
MEAN Stack has a hopeful future : A lot of companies are switching to MEAN, as it allows low-cost development and delivery of applications to save on costs and increase efficiencies. Due to its open-source nature MEAN offers a wider range of applications, which is the key feature for it to get accepted in the coming time.
Understanding both Front-end and Back-end processes is a must if you want to become a MEAN Stack developer. You need to have a good hold of HTML and CSS, it will lay a great foundation for you to begin with.
Then you will need to focus on your key skills of JavaScript and JSON. Next have a good knowledge of Node.JS, Express.JS, and Angular.JS
