What's the use case? Relying on the order of the properties in the object
is almost always a bad idea (although if I read the current spec correctly,
`Object.keys` is no longer exempt from order as it once was). The only time
I've seen this done that seemed reasonable was when the object was known to
have a single own enumerable property but that property's name was unknown
(which was, in itself, an X/Y problem -- the real problem was why that name
was unknown/varied at runtime).
