Javascript Hoisting explains how JS with automatically bring your variables above other code for cache purposes. This may end up effecting your scope and shadowing of variables. or accidentally rewriting a variable.

You will have to elaborate on your question please.

I second Phillip Cox's answer.

Also, we have no idea what you're asking. What's confusing about it? Phillip did a pretty good job explaining hoisting.

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

I've tried all different combinations and cannot get this answer. Where do we define the variable? I would think it needs to be defined before the function but also called after the if statement in the function as well.. Any help is appreciated!
