Day 125 of Learning MERN Stack

During days 124 to 128 of a MERN Stack marathon, a Social Media Post Dashboard was built using useState, useRef, Context API, and useReducer. The project evolved by replacing mock lists with live third-party servers via Fetch API and Async/Await. Performance was optimized using useEffect Cleanup and AbortController to prevent memory leaks. Finally, a Real-Time Clock Application was engineered to manage persistent browser loops and Timer Cleanups, ensuring efficient background processing without triggering processor spikes.
