How can I improve the performance of my React custom hooks?
To improve performance, consider memoizing your hooks using useMemo
or useCallback
to prevent unnecessary re-renders.
What are some common pitfalls when using custom hooks?
Common pitfalls include not properly managing dependencies in effect hooks and causing excessive re-renders.
Can you give an example of a performant custom hook?
Sure! A custom hook that fetches data and uses useMemo
to cache results can enhance performance significantly.
How do I test the performance of my custom hooks?
You can use React's Profiler API to measure the rendering time and identify performance bottlenecks in your custom hooks.
