1. Let _baseReference_ be the result of evaluating |MemberExpression|.
|
|
2. Let _baseValue_ be ? GetValue(_baseReference_).
|
|
3. Let _fieldNameString_ be the StringValue of |PrivateIdentifier|.
|
|
4. Return ! MakePrivateReference(_baseValue_, _fieldNameString_).

PutValue (V, W)

5.b. If IsPrivateReference(_V_) is *true*, then
|
|
i. Return ? PrivateSet(_baseObj_, _V_.[[ReferencedName]], _W_).
|
|
|
|
PrivateSet (O, P, value)
|
|
...
|
|
5.a. Assert: _entry_.[[Kind]] is ~accessor~.
|
|
b. If _entry_.[[Set]] is *undefined*, throw a *TypeError* exception.
