If you understand hoisting as a characteristic of JavaScript, its behavior is very predictable, and thus, hardly broken -- merely tricky if you've yet to encounter a hoisting-related issue.
That said, I find almost any issue with writing JavaScript can be easily mitigated by utilizing JSHint, and you get the added benefit of sticking with the base language, which is better because if you're writing raw JS everyday, your skills are more transferable than if you're writing CS every day if only for the fact that you can still write JS in a CS-only stack, but you can't write CS in a JS-only stack.
