What is the MERN Stack and How Does It Work?

The MERN stack is a powerful web development framework that combines four technologies: MongoDB, Express.js, React, and Node.js. This full-stack JavaScript solution allows developers to build dynamic, high-performance applications efficiently. MongoDB serves as the NoSQL database, storing data in flexible, JSON-like documents. Express.js acts as the web framework for Node.js, facilitating routing and middleware. React enables the creation of interactive user interfaces, while Node.js handles server-side operations, ensuring smooth communication between the client and server. Together, these technologies provide a robust ecosystem for developing modern web applications.
