What are some common mistakes to avoid when using React?
Some common mistakes in React include not using keys in lists, improper state management, and not optimizing performance.
Can you explain why using keys in lists is important?
Using keys helps React identify which items have changed, are added, or are removed, improving performance and preventing bugs.
What about state management? What mistakes should I avoid?
Avoid mutating state directly, as it can lead to unexpected behavior. Always use setState or the updater function.
How can I optimize performance in my React app?
You can optimize performance by using React.memo, lazy loading components, and avoiding unnecessary re-renders.
