Not sure if this is too early; but I like the idea of the symmetry with existing length and size keywords on arrays and maps.

Are properties like:

• Object.length(...)
• Object.size(...)

possible?

My logic would be that if you're already used to doing Object.keys().length you would think of it because of the same name.

Wouldn’t it be confusing that length and size are properties everywhere else, and a function here?

That could be an issue, but propertyCount isn't a verb either so also could be misconstrued as a getter.
