union([1, 2, 3], [2, 3, 4]); //=> [1, 2, 3, 4]

union(['a'], ['b']);
// => ['a', 'b']

union([1], ['1', 1]);
//=> [1, '1']

union([{ a: { b: 10 } }], [{ a: { b: 20 } }]);
//=> [{a: { b: 10 }}, {a: { b: 20 }}]

union([{ a: { b: 10 } }], [{ a: { b: 10 } }]);
//=> [{a: { b: 10 }}]

union([{b: 10, c: {z: {t: 5, _t: 5}, f: [4]}}, 2], [{b: 10, c: {z: {t: 5, _t: 5}, f: [ 4]}}, '2']);
//=> [{b: 10, c: {z: {t: 5, _t: 5}, f: [4]}}, 2, "2"]
