Why not both? My point is that Map/WeakMap do a lot of what people historically use Object for, but in a better way; certainly, they solve Tadas's issue here.
The trouble is that Objects have a lot of convenient sugar around them that make them easier, and more pleasant, to use. We really shouldn't be in a position where people choose the worse option simply out of sugar. -------------------------- Dammit babies, you've got to be kind.
