			Running eslint with --fix didn't fix many of the issues. The majority here had to be fixed by hand but a significant majority of the issues were related to a few files that I was able to use find-and-replace with. I regret not making this in to separate commits of the hand-fixes and the fixes from --fix but I don't recall --fix fixing any of the issues.
