Mean

MEAN is an open-source full-stack JavaScript development stack used for building dynamic, scalable, and modern web applications. It combines MongoDB for database management, Express.js for backend application development, Angular for frontend user interfaces, and Node.js as the server runtime environment. MEAN enables developers to use JavaScript across the entire application stack, simplifying development, improving code reusability, and streamlining deployment processes.

• Provides a complete JavaScript-based full-stack development environment.
• Uses MongoDB for flexible and scalable NoSQL database storage.
• Supports Express.js for building RESTful APIs and backend services.
• Includes Angular for creating responsive and interactive frontend interfaces.
• Uses Node.js for high-performance and event-driven server-side execution.
• Supports real-time application development with asynchronous processing.
• Enables code sharing and consistency across frontend and backend layers.
• Allows integration with third-party packages and modern development tools.

Verify the MEAN environment , run:
$sudo su
$node -v
$npm -v
$ng version
$mongod --version

Disclaimer: MEAN is a collection of independently maintained technologies. Compatibility between MongoDB, Angular, Node.js, and related packages may vary across versions. Always verify package compatibility and dependency requirements before deploying applications in production environments.
