The Code tab has a code which attempts to add a clone of an array to itself. There is no error message, but the results are not as expected. Can you fix the code?
clone([5, 44]) ➞ [5, 44, [5, 44]]
clone([4, 666]) ➞ [4, 666, [4, 666]]
clone([1, 1]) ➞ [1, 1, [1, 1]]
clone([1, 2, 3]) ➞ [1, 2, 3, [1, 2, 3]]
clone(["x", "y"]) ➞ ["x", "y", ["x", "y"]]N/A
