usecallback vs usememo

Comment

useCallback and useMemo -
  
  both for optimization in react.
  
useCallback - caches a callback (function) to keep its previous reference.
            - referential equality between renders
            - if function is passed as props, will not re-render the component if wrapped with react.memo
            - since function reference did not change


useMemo     - similar to useCallback but this hook caches a value or result
		    - does no recompute if dependency array did not change resulting to optimized performance

  both for optimization in react.
 
useCallback - It caches the provided function instance 0.
			 - when need to cache a function useCallback
useMemo -It invokes provided function and caches it's result.
        - wen you need to cache the result of an invoked function useMemo
