I see, thanks.
So, from what I see:
1. Source should not be the one. We should support many of sources to copy all
them at once:
Object.assign(dest, source1[, source2, ... sourceN])
In addition:
2. If the last parameter is boolean, then it's created as includeNonEnumerable:
Object.assign(desc, source1[, source2, ... sourceN, includeNonEnumerable);
Example;
Object.assign({a: 10}, {b: 20}, Object.defineProperties({}, {c: {value: 30}}),
true); // {a: 10, b: 20, c: 30}
