min:
                                [1] -> 1
                    [5, 1, 2, 3, 4] -> 1
                    ["a", "b", "c"] -> "a"
                        ["20", "3"] -> "20"
                        ["3", "20"] -> "20"
                            [20, 3] -> 3
                            [3, 20] -> 3

min of empty array is undefined:
                                 [] -> undefined
                             [null] -> undefined
                        [undefined] -> undefined
                              [NaN] -> undefined
                         [NaN, NaN] -> undefined

min ignores null, undefined, and NaN:
               [NaN, 1, 2, 3, 4, 5] -> 1
               [1, 2, 3, 4, 5, NaN] -> 1
   [10, null, 3, undefined, 3, NaN] -> 3

min compares heterogenous types as numbers:
                          [20, "3"] -> "3"
                          ["20", 3] -> 3
                          [3, "20"] -> 3
                          ["3", 20] -> "3"

min applies accessor function:
  [1, 2, 3, 4, 5], [2, 4, 6, 8, 10] -> 5
                    [1, 2, 3, 4, 5] -> 0
