  1. Be careful.
    The first example using useEffect without dependencies array (it should be [handleClickOutside] or []) will be called on each render.
    The second one using class is wrong, .bind(this) creates a new reference and the listener will never be removed on componentWillUnmount.
    Use fat arrow function or binding on constructor, but never use .bind for events listeners !

    1. Thank you very much for these great suggestions. I updated code with binding in constructor. Also, I improved the hook-based example code by destructing props and putting handleClickOutside into useEffect as recommended in React Hooks FAQ docs.

  2. Is there a way to make it so the tooltip disappears when you click on either button or the component after already clicking it
