I'm doing a method that return element that appears earlier in array

// def first_in_array(arr, el1, el2) if arr.index(el1) < arr.index(el2) return el1 else return el2 end

end

puts first_in_array(["a", "b", "c", "d"], "d", "b"); # => "b" puts first_in_array(["cat", "bird" ,"dog", "mouse" ], "dog", "mouse"); # => "dog"

//

Why el1 => b ?

isnt it supposed that el1 = d and el2 = b ?

since el1 is index 1
