With their release, Hooks gave function components the ability to use state and side-effects with built-in Hooks such as React's useState Hook and React's useEffect Hook . There are only a handful built-in Hooks (e.g. useReducer , useCallback , useMemo , useContext ) provided by React though…
In this React tutorial, you will learn how to store state in local storage by using a custom React Hook . We will address the session storage shortly as well, but essentially it is used the same way as the local storage in React.

A neat custom React Hook that I used in some of my React freelance projects which gets you the scrollbar's width.
