  1. Custom events are also known as “synthetic” events.

    You need to check this statement. Synthetic events are react wrappers over native HTML events. Custom events are what you described in your article.

  2. For unsubscribe to work you need to pass the initial function. So unsubscribe(“hideList”); need the pointer to the function.

    So:
    let f = setIsOpen(false);
    subscribe(“hideList”, f);

    and later:
    return () => {
    unsubscribe(“hideList”,f);
    }
