--description--
Given an array with two values, return an array with the values swapped.
For example, given ["A", "B"] return ["B", "A"].
--hints--
arraySwap(["A", "B"]) should return ["B", "A"].
assert.deepEqual(arraySwap(["A", "B"]), ["B", "A"]);
arraySwap([25, 20]) should return [20, 25].
assert.deepEqual(arraySwap([25, 20]), [20, 25]);
arraySwap([true, false]) should return [false, true].
assert.deepEqual(arraySwap([true, false]), [false, true]);
arraySwap(["1", 1]) should return [1, "1"].
assert.deepEqual(arraySwap(["1", 1]), [1, "1"]);
