Would like to maintain a map/hash of DOM objects. Can they serve as key objects? If not, what are the alternatives, please? If there are better ways – kindly enlist them as well.

You can put anything as the key, but before actual use it is always converted to string, and that string is used as a key.
So, if you look at what
domObject.toString()produces, you see it is not a good candidate. If all of your dom objects have an id, you could use that id.If not, and you still desperately need a key based on DOM object, you probably could do with using, for example,
_counterattribute with automatic counter in background putting new unique value in a DOM object if_counteris not yet present.
