print(ee.List(['dog']).cat(['squirrel'])); // ["dog","squirrel"]
print(ee.List(['moose']).cat(['&', 'squirrel'])); // ["moose","&","squirrel"]
print(ee.List([['a', 'b']]).cat(ee.List([['1', 1]]))); // [["a","b"],["1",1]]
print(ee.List([]).cat(ee.List([]))); // []
print(ee.List([1]).cat(ee.List([]))); // [1]
print(ee.List([]).cat(ee.List([2]))); // [2]
