My React application becomes slow as it grows. What are the best practices for improving performance? I'd like to learn about React.memo, useMemo, useCallback, lazy loading, and code splitting.

React performance can be improved by using React.memo to prevent unnecessary re-renders, useMemo and useCallback to memoize values and functions, lazy loading with React.lazy, code splitting, list virtualization, and minimizing unnecessary state updates. These techniques help create faster and more efficient applications.
