OrdinaryPreventExtensions ( O )
1. Set O.[[Extensible]] to false.
Object.assign ( target, ...sources )
[...]
3. For each element nextSource of sources, do
a. If nextSource is neither undefined nor null, then
[...]
iii. For each element nextKey of keys, do
1. Let desc be ? from.[[GetOwnProperty]](nextKey).
2. If desc is not undefined and desc.[[Enumerable]] is true, then
[...]
b. Perform ? Set(to, nextKey, propValue, true).

[...]
3. If IsDataDescriptor(ownDesc) is true, then

c. Let existingDescriptor be ? Receiver.[[GetOwnProperty]](P).
d. If existingDescriptor is not undefined, then

iii. Let valueDesc be the PropertyDescriptor { [[Value]]: V }.
iv. Return ? Receiver.[[DefineOwnProperty]](P, valueDesc).

9. If O is not undefined, then
a. For each field of Desc that is present, set the corresponding attribute
of the property named P of object O to the value of the field.
