I've just tested your solution and it passed the kata without any errors, so closing...

This isn't really a solution, it's basically a cheat. It isn't doing what you think it's doing.

I guess you're asking about JavaScript. That example would look like eqAll({}) => false. It's an iterable. It doesn't (necessarily) have keys or values, you must iterate it.

The link that is already in the description points to some documentation.

If argument is only a string you should compare each chars of this string, eg :

max("AZBYC") // return "Z" because when comparing "Z" to "A" or "Z" to "X", "Z" is usually considered "greater"

If argument is an array of strings simply compare each string with others, eg :

max("abc", "abcd", "abd", "Aaa" ) // should return "abd" because "abd" > "abc.." > "A..." ("d" greater than "c" & "a" greater than "A")

Hope it helps.
