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
