The Challenge

The primary hurdle was managing complex React state and ensuring precise time intervals without performance degradation or memory leaks. I utilized React Hooks (`useState`, `useEffect`) to seamlessly manage the timer's lifecycle, process clear start/stop/reset actions, and accurately calculate lap differences dynamically.
