The MERN stack is a popular and powerful technology stack used for building full-stack web applications. It consists of four main technologies: MongoDB, Express.js, React.js, and Node.js. Each component of the MERN stack serves a specific purpose in the development process, allowing developers to create dynamic and scalable web applications efficiently.
- MongoDB: NoSQL database storing data in JSON-like documents.
- Express.js: Web application framework for Node.js, simplifying server-side development.
- React.js: JavaScript library for building user interfaces.
- Node.js: JavaScript runtime for server-side applications.
