UPDATE: This answer (the text below) was wrong despite being the accepted answer. Instead of comparing the IDs use an equality check of the elements: element1 === element2

If the Ids are the same, they cannot be different. If the Ids are different they cannot be the same. So if you have both Ids you can just compare the two Ids.
