MERN stack is a popular and widely used technology stack for building web applications. MERN Stack development is particularly popular for developing single-page applications (SPAs) and is known for its efficiency, flexibility, and the ability to create modern, dynamic web applications. It's an acronym that represents a combination of four key technologies:
1. MongoDB
This is a NoSQL database that stores data in a flexible, JSON-like format. MongoDB is known for its scalability and ability to handle large amounts of data. It's commonly used for storing the structured and unstructured data of web applications.
2. Express
This is a back-end web application framework for Node.js. It simplifies the process of building web applications and APIs by providing a set of tools and features for routing, middleware, and other common web application functions. It's lightweight and helps with the organization and structuring of your server-side code.
