Variables Challenge Task 1

I'm kind of at a loss on this one.

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

function elevatorCloseButton(pushed) {

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

    }

Ok, the difference is in your case, your variable status is only accessible within the function. Mine was a global variable and can be accessed everywhere. In fact I didn't read correctly this part of your sentence "within the scope of the function."

My fault ;)

Try something like that

var status= "";

function elevatorCloseButton(pushed) {

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

    }

Declare the variable outside the function and then if (pushed) , if true, update the content of this variable.

Ok gotcha, thanks!

This ended up working:

function elevatorCloseButton(pushed) {

       var status= "";

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

}
