4a9f15f seems pretty unrelated and subjective (I tend to favor double quotes always since there’s no reason not to) and makes this diff pretty hard to review. Can we pull that out into another PR if you’re heart-set on it?

True, but just trying to get some sort of consistency throughout the project. But I can move these changes to the Coffeelint PR (#2738)

I prefer single, because it doesn't require me to press shift to type it.

But I removed that commit, do you have anything else to add to this? :)
