The MERN Stack is one of the most popular web development stacks today. It consists of MongoDB, Express.js, React.js, and Node.js, allowing developers to build full-stack JavaScript applications from the front-end user interface to the back-end server and database.



MERN is widely used because of its single-language development (JavaScript), high performance, and flexibility for building scalable web applications. Whether you are a beginner looking to learn web development or preparing for technical interviews, having handwritten notes and interview question collections can significantly accelerate your learning.
