Why does Object.keys() not allow, as an option, iterating through
inherited properties?
I do not have the answer to this very question.
However, if you want to iterate through all (own and inherited)
enumerable properties, you can use a for-in loop.
Right, but for that matter, if you want Object.keys, you can just
write out a for-in loop as well and just do .hasOwnProperty().
Object.keys must be considered a convenience method; it just seems
like there are lots of reasonable scenarios of wanting the inherited
properties as well as the object’s own.
Object.allKeys(), anyone?
Object.getPropertyNames from
http://wiki.ecmascript.org/doku.php?id=harmony:extended_object_api ?
Or do you want to filter out non-enumerable properties?
Yes. ISTM there’s a legitimate case for putting a key-lister function
that includes all inherited, non-enumerable properties.
