Re: Property ordering of [[Enumerate]] / getOwnPropertyNames()

This doesn't answer the spec question, exactly, but v8 doesn't currently conform to ES6's requirements for [[OwnPropertyKeys]]: some objects return names in an implementation-dependent order (see https://code.google.com/p/v8/issues/detail?id=3056 for more details). On Thu, Aug 20, 2015 at 9:54
