When working with a dynamic number of components, React asks developers to provide a unique key, lest this error is thrown:
Each child in a list should have a unique "key" prop
Say that each child shows a different icon and label based upon some prop. Does the usage of useMemo here have any impact on performance?
"useMemo will only recompute the memoized value when one of the dependencies has changed." - from React docs
Given that the elements dependencies (state, props) are still the same and nothing has changed the performance benefit should not be negated.
