5,352 PointsI am having trouble with the JavaScript foundations variables code challenge
The question asks me to "Alter the 'elevatorCloseButton' function to follow the best practices in declaring variables within the scope of the function." After moving the var status to under the function and assigning status to "I'll close when I'm ready." It still asks me to "assign the status variable in the if statement" what am I doing wrong?

Yes, but what have you tried? I can post the code to solve the task, but would love to see what you have tried.

Perfect, thanks for posting your code.
The challenge tasks asks us to:
Alter the 'elevatorCloseButton' function to follow the best practices in declaring variables within the scope of the function.
You don't want to define the variable initially, just declare it, so the code snippet would look like:
// Hoisting Code Challenge
<script>
function elevatorCloseButton(pushed) {
var status;
if (pushed) {
status = "I'll close when I'm ready.";
}
}
elevatorCloseButton(true);
</script>
Happy coding, Ken

3,903 PointsHmmm... interesting, thank you much Ken Alger ! I was having issues with that particular hoisting challenge as well. I didn't have the same mark up issues as Dylan Moberg , but your clarification definitely made sense and worked for me as well.

Can you post the code you are using? It sounds like you are very close, but without seeing the exact code it is difficult to diagnose the issue.
Thanks,
