iterating through object property values
It seems the typical way to do this is:
Object.keys(myObj).forEach(key = {
let value = myObj[key];
// Do something with value and/or key.
});
I don't see a new way to do this in ES6.
Is it still being considered to add the methods entries and values to
Object that return iterators?

Re: iterating through object property values
It seems a bit late to add a default @@iterator to Object.prototype, but I
guess it could work similar to Map.prototype.entries, if such a thing were to
be added.
Have to be really careful adding things to Object.prototype, though — even when
they’re non-enumerable, they can cause unexpected problems in code (code which
probably ought to be using Object.create(null), but you know, doesn’t).

Being a Symbol rather than a String property key probably mitigates most of
these problems, but I’m not positive about that.

Re: iterating through object property values
for (key of Reflect.ownKeys(myObj)) {
//Do something with key or myObj[key]
}
