How can you reduce unnecessary re-renders in large React applications?

To reduce unnecessary re-renders in large React applications:

• Use React.memo: Wrap functional components to prevent re-renders when props haven't changed.
• Implement shouldComponentUpdate: For class components, this lifecycle method can be overridden to control rendering behavior.
• Utilize useMemo and useCallback Hooks: Optimize performance by memoizing values and functions, reducing reference changes.
• Split components: Break down large components into smaller ones to isolate state and avoid triggering re-renders in sibling components.
• Optimize Context usage: Limit context consumers or segment context values to avoid re-renders of all consumers when only one value changes.
