There are several strategies to optimize large list rendering in React: 1. **Virtualization**: Use libraries like react-window or react-virtualized to render only visible items. 2. **Memoization**: Wrap list items with React.memo() to prevent unnecessary re-renders. 3. **useMemo for calculations**: If you're doing expensive calculations, wrap them in useMemo. 4. **Pagination or infinite scroll**: Load data in chunks instead of all at once. Would you like me to show you an example implementation?
