How does conditional rendering in JSX affect performance?
Conditional rendering in JSX can impact performance based on how it's implemented. Using techniques like memoization can help.
What are some best practices for optimizing conditional rendering?
Best practices include using React.memo, avoiding inline functions, and minimizing state updates to reduce re-renders.
Can you explain how React.memo works?
React.memo is a higher-order component that prevents unnecessary re-renders by memoizing the component's output based on props.
Are there any tools to analyze performance in React applications?
Yes, tools like React DevTools and performance profiling in Chrome can help analyze and optimize React app performance.
