Performance Optimization in MERN Stack Applications

This paper focuses on improving the performance of web applications built using the MERN stack (MongoDB, Express.js,React, and Node.js).It identifies common performance issues in each part of the stack and provides practical solutions, such as speeding up database queries, optimizing server code, improving how React handles components, and balancing server loads.Through real-world examples, the paper shows how these techniques can make applications faster, more efficient, and better able to handle more users.
