What is the purpose of useCallback Hooks?
The purpose of useCallback Hooks is used to memoize functions, and prevent unnecessary re-rendering of child components that rely on those components. The useCallback function in React is mainly used to keep a reference to a function constant across multiple re-renders. This feature becomes useful when we want to prevent the unnecessary re-creation of functions, especially when we need to pass them as dependencies to other hooks such as useMemo or useEffect.
