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.

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.
