React Todo application

React application with advanced performance optimization.

Implemented component memoization through React.memo, useMemo, and useCallback to eliminate redundant renders. Added lazy loading and code splitting.

Achieved improvements:
- Rendering speed increased by 2.5 times
- Optimization for working with large lists (1000+ items)
- Memory consumption reduced by 35%

Used React DevTools Profiler to measure performance and identify bottlenecks.
