One thing about scope hoisting in JS is that it allows to simulate some aspects of functional programming, where the the order of execution does not necessarily math the order of declaration. I use this all the time to order code elements in a file in order of decreasing importance.

I wish there was explicit support for this though, maybe with a construct like <exression> where <antecedent>, etc, like what Haskell has, instead of having to hack it using functions and var
