How can I improve performance with conditional rendering in React?

How can I improve performance with conditional rendering in React?

To improve performance, consider using React's memoization techniques like React.memo and useMemo to prevent unnecessary re-renders.

What are some common pitfalls with conditional rendering?

Common pitfalls include excessive re-renders, not using keys properly in lists, and rendering too many components conditionally.

Can you give an example of using React.memo?

Sure! You can wrap a functional component with React.memo to memoize it. For example: const MyComponent = React.memo((props) => { /* render logic */ });.

How does useMemo help with performance?

useMemo helps by memoizing the result of a computation, so it only recalculates when its dependencies change, reducing unnecessary calculations.
