What’s The Meaning of MEAN?
Before you bring on a company to do MEAN stack development services for you, it’s important to understand that MEAN is the perfect fusion of four powerful frameworks:

MongoDB allows for effective data management for websites.

Express.js is specially designed for multipage and hybrid web applications.

Angular provides a modern looking user-interface and enables a great user experience. Being JavaScript based but harnessing new technologies you get the best of both worlds.

Node.js enables us to write server side logic to build the backbone of any application.
Coined in 2013 by MongoDB’s Valeri Karpov, the term “MEAN Stack” simply refers to the four technologies that make up the layers of the “stack.”
