usecallback vs usememo

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
            

react usememo vs usecallback

useMemo is to memoize a calculation result between a function's calls and between renders
useCallback is to memoize a callback itself (referential equality) between renders

usememo vs usecallback

---- useMemo vs useCallback -----------------------------------------

useMemo: memoize A CALCULATION RESULT between a function's calls
and between renders.

useCallback: memoize A CALLBACK ITSELF (referential equality) 
between renders.
