5. If IsPropertyReference(V), then

...

|
|
b. If IsPrivateReference(V), then
|
||
|
|
i. Let env be the running execution context's PrivateNameEnvironment.
|
||
|
|
ii. Let field be ? ResolveBinding(GetReferencedName(V), env).
|
||
|
|
iii. Assert: field is a Private Name.
|
||
|
|
iv. Return ? PrivateFieldGet(field, base).
|
||
|
|
c. Return ? base.[[Get]](GetReferencedName(V), GetThisValue(V)).

|
|
PrivateFieldGet(P, O)
|
||
|
|
1. Assert: P is a Private Name value.
|
||
|
|
2. If O is not an object, throw a TypeError exception.
|
||
|
|
3. Let entry be PrivateFieldFind(P, O).
|
||
|
|
4. If entry is empty, throw a TypeError exception.
|
||
|
|
5. Return entry.[[PrivateFieldValue]].
