What are common re-rendering issues in React?
Common re-rendering issues in React include unnecessary renders due to state changes, improper use of keys in lists, and not using memoization.
How can I optimize my components to prevent unnecessary re-renders?
You can use React.memo for functional components, PureComponent for class components, and useCallback or useMemo hooks to optimize performance.
What tools can help me identify re-rendering issues?
You can use React DevTools to analyze component re-renders, and tools like why-did-you-render to track unnecessary renders.
Are there any best practices to follow for managing state?
Yes, keep state local where possible, lift state up when needed, and consider using context or state management libraries for global state.
