Please, please, stop using "foo" and "bar” in code documentation. Give us real examples that mean something. Not "if (foo > bar)," but “if (height > limit)." Not “foo++” but “counter++”. Give us a logical hook to hang our hat on, not nonsense words.
Oh good it's not just me who can't make sense of their docs. Just started trying to use jq to solve an issue, now I have three issues.
