JavaScript JavaScript Foundations Variables Hoisting

Confused with what the challenging is asking...

I am currently stuck with the following question. I tried to put the "var status" in different places within the elevatorCloseButton function but I keep getting it wrong.

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

<!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) {

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

}

elevatorCloseButton(true);

</script>

</body> </html>

First declare the variable status inside the function then inside the if statement you can define it.

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

}

Hey Yi Ren,

In the video, Hoisting with Jim Hoskins, best practices here would be to define your variables at the top of the function the way Jeremy Faith has done

  var status;

and later assign a value to the variable that is "status"

 status = "I'll close when I'm ready.";

Hope that helps ;)
