The Props Collection Pattern in Practice

export default function useExpanded () {
  const [expanded, setExpanded] = useState(false)
  const toggle = useCallback(
    () => setExpanded(prevExpanded => !prevExpanded),
    []
  )
  // look here 👇
  const togglerProps = useMemo(
    () => ({
      onClick: toggle,
      'aria-expanded': expanded
    }),
    [toggle, expanded]
  )
  ...
  return value
}
