The order of keys is the same order of array in input

Objects do not have key order in general.

and the order of alerts is left to rigth top to bottom

This is not properly tested: sorting by y first or x first both passes the tests.

Also this description is not properly formatted at all (and not even coherent in the first place), it screams to be rewritten.

Distance metric is not specified, and frankly insane: why is Chebyshev distance used??? Shouldn't any sane person be able to deduce that distances in reality are in Euclidean distance?

Nice Kata.

• Somewhere in description Storm is spelled wrongly as Strom.
• Need random tests. See https://github.com/Codewars/codewars.com/wiki/Codewars-JavaScript-Test-Framework#utilities
• You swapped the arguments in Test.assertEquals(actual, expected[, msg]).
• In Headlines format, a whitespace is required between # and the text.
