MERN stack development refers to building web applications using MongoDB (database), Express.js (backend framework), React.js (frontend library), and Node.js (runtime environment).

MERN stack is popular because it uses JavaScript throughout, making development efficient. It also has a strong community, high scalability, and seamless integration between components.

Key skills include proficiency in JavaScript, React.js, Node.js, Express.js, MongoDB, REST APIs, authentication, deployment, and version control (Git).

MongoDB is a NoSQL database that stores data in JSON-like documents, allowing flexible schemas. SQL databases use structured tables with predefined schemas.

Express.js is a lightweight backend framework for Node.js. It simplifies server-side development by handling routing, middleware, and APIs efficiently.

React.js offers a component-based architecture, virtual DOM for better performance, and a rich ecosystem for building dynamic and interactive UIs.

Authentication can be implemented using JWT (JSON Web Token), OAuth, or Passport.js for secure login and access control.

Node.js provides a runtime environment for executing JavaScript outside the browser. It enables server-side development with high scalability and efficiency.

MERN apps can be deployed using platforms like Vercel, Netlify (frontend), and Heroku, AWS, or DigitalOcean (backend and database).

Optimize queries in MongoDB, use caching, compress assets, enable lazy loading in React, and follow clean coding practices.
