Avoid unnecessary rendering: When a function is passed as a prop to a child component, you can use useCallback to ensure that the function is only recreated when its dependencies change, thus avoiding unnecessary rendering.
Enhancing performance: When a function is needed in multiple places and its dependencies remain constant, useCallback can be used to cache the reference of the function, preventing redundant creations.
Passing as a dependency to other hooks: When a custom hook depends on a function, you can use useCallback to ensure that the function is recreated when the dependencies change, thereby avoiding side effects.
Handling inline functions: To pass an inline function as a prop to a child component, you can use useCallback to prevent creating a new function instance on every render.
