Gain insights into advanced React patterns with hooks. Learn about optimizing components with hooks over traditional methods like render props or higher-order components for better efficiency.

With the release of hooks, certain React patterns have gone out of style. Hooks are likely the way we’ll be writing React components for the next couple of years, so they are quite important. React patterns can still be used, but in most cases, developers will be better off using hooks. For example, they should choose hooks over render props or higher-order components. There may be specific cases where the aforementioned could still be used, but most of the time, hooks are better. That being said, this course will teach you some of the more advanced React patterns implemented with hooks.

Advanced React Patterns With Hooks

# The Props Collection
Take a look at the props collection for the `useExpanded` hook:  

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
}

Within `useExpanded` we’ve created a new memoized object, `togglerProps`, which includes the  `onClick` and `aria-expanded` properties. 

Note that we’ve called this props collection  `togglerProps` because it is a prop collection for the toggler, i.e., the toggle element, regardless of which UI element it is. 

We’ll then expose the `togglerProps` from the custom hook via the returned `value` variable. 

Let's apply the props collection pattern to our expandable component!
