JavaScript JavaScript Foundations Variables Hoisting

I'm not sure of what is being asked

The Challege question is "Alter the 'elevatorCloseButton' function to follow the best practices in declaring variables within the scope of the function".

Not sure how to answer this question:

    <script>

    function elevatorCloseButton(pushed) {

        if (pushed) {
            var status = "I'll close when I'm ready.";
        }

    }

    elevatorCloseButton(true);

    </script>

function elevatorCloseButton(pushed) {
var status;
        if (pushed) {
            status = "I'll close when I'm ready.";
        }

    }

    elevatorCloseButton(true);

I think this is an answer. You should always declare variable at the beginning and set value later when you need it.

Right before the if statement, try adding var status;
