MEANβs appeal is mostly due to its uniformity, which refers to the fact that it is entirely written in JavaScript. Developersβ lives are made easier because every component of the application is written in the same language, from database objects to client-side code.
This uniformity contrasts with the mishmash of LAMP, a protracted favorite of web application developers. LAMP, like MEAN, is an abbreviation for the stackβs components: Linux, Apache HTTP Server, MySQL, PHP, Perl, or Python. Several of the stackβs pieces have little to share with the others.
This isnβt to suggest that the LAMP stack isnβt capable. Itβs still widely used, and each component of the stack has a thriving development community. MEAN, on the other hand, provides conceptual consistency, which is a huge plus. It becomes easier for a developer to grasp the entire stack at once if all layers of the stack use the same language and many of the same language principles.
The database, the front end, the back end, and the execution engine are all present in most MEAN stacks. This does not imply that the stack is made up entirely of these pieces, but they do form the foundation.
