This suggests to have a convenience method like getOwnProperties that return an array of ptoperty descriptor for the object. It would allow a user to define a simple form of the extend method as: Object.defineProperties(destination, Object.getOwnProperties(source)); It would also allow to define Object.clone(source) precisely as Object.create(Object.getPrototypeOf(source), Object.getOwnProperties(source)); Which in fact shows that Object.clone is in the same category as Object.extend. Both methods defines very particular arrangement of properties in the object and less fundamental than the rest sets of the methods.
