## Introduction to the MERN Stack



In this section, you'll learn about the MERN stack's components and how they work together to build modern web applications.



## MongoDB



MongoDB is a NoSQL database that stores data in a flexible, JSON-like format. It's designed for scalability and handling large amounts of unstructured data.



## Express.js



Express.js is a web application framework for Node.js. It simplifies building robust APIs and handling routes, middleware, and HTTP requests.



## React



React is a JavaScript library for building user interfaces. It utilizes a component-based architecture to create reusable UI components and manage dynamic views.



## Node.js



Node.js is a runtime environment that enables server-side JavaScript execution. It's used to build scalable and efficient network applications.



## RESTful APIs



Learn about designing RESTful APIs that adhere to the principles of Representational State Transfer (REST). Understand HTTP methods, status codes, and API design best practices.



## Authentication and Authorization



Explore techniques for implementing user authentication and authorization in MERN applications. Learn about JWT (JSON Web Tokens), OAuth, and security considerations.



## State Management



Discover various state management approaches in React applications. Compare local state, React's Context API, and third-party libraries like Redux for managing global state.



## Deployment



Learn how to deploy MERN applications to various platforms like Heroku, AWS, or Netlify. Understand the deployment process, environment variables, and scaling considerations.



## Interview Tips



Get valuable tips for your MERN stack interviews, including common interview questions, how to showcase your theoretical knowledge effectively, and demonstrating problem-solving skills.



## Additional Resources



Explore a curated list of books, online courses, tutorials, and websites that provide in-depth insights into MERN stack development and interview preparation.
