Alter the 'elevatorCloseButton' function to follow the best practices in declaring variables within the scope of the fun

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

    elevatorCloseButton(true);

Why it is wrong?

So what you need to do is declare the variable first then inside the if statement change the variable. So something like this would work.

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

    }

    elevatorCloseButton(true);

See how the var is declared first and then changed by dropping the keyword var in the if statement. This would make it easier if you had an else statement to change the same variable again with the same method.

Thanks, Adam. I was stuck on this and couldn't figure out the solution based off the prompts being given in the challenge.
