Question

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

What do I have to do?

    <script>

function elevatorCloseButton(pushed) {

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

}

elevatorCloseButton(true);

</script>

index.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <title> JavaScript Foundations: Variables</title>
    <style>
      html {
        background: #FAFAFA;
        font-family: sans-serif;
      }
    </style>
  </head>
  <body>
    <h1>JavaScript Foundations</h1>
    <h2>Variables: Hoisting</h2>

    <script>

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

        if (pushed) {
            status;
        }

    }


    </script>
  </body>
</html>

Try declaring an unassigned variable at the top of the function.

And then assigning it's value by defining the variable again only this time don't include the var keyword. This is trying to give you practice in "hoisting" a variable. :-)
