MEAN stands for MongoDB, Express.js, Angular and Node.js - a streamlined JavaScript pipeline from database to user interface. You avoid switching languages and can keep everything in JS for a smooth workflow.

Picture a project where the database (MongoDB), server logic (Express on Node.js) and frontend (Angular) all live in a single cohesive environment. It’s convenient and cleanly structured thanks to a shared language across layers.

MEAN’s appeal is the “JavaScript everywhere” philosophy: working with the same language on both backend and frontend yields a more consistent and efficient development rhythm. There are plenty of starter kits and guides to help you get going, especially if you already know JavaScript.
