How to Use useCallback to Improve React Native Performance
How to Use useCallback to Improve React Native Performance Memoizing a callback function is made possible by the useCallback hook in React. This indicates that the callback will only be recreated if one of the passed hook dependencies has changed. Performance optimization can benefit from this, particularly when passing callback props to child components. You must pass two arguments to the useCallback hook in order to use it: the callback function and a list of its dependencies. If any of the dependencies have changed, The hook will return a new callback function that will only be recreated if any of the dependencies have changed.. For example: const myCallback = useCallback(() => { // Do something }, [dependency1, dependency2]); After that, you can pass myCallback to a child component as a prop. Only if either dependency1 or dependency2 changes will the child component re-render. Keep in mind that the dependency array should not contain any props or state variables...
