info: |
PrivateFieldGet (P, O)
1. Assert: P is a Private Name.
2. If O is not an object, throw a TypeError exception.
3. If P.[[Kind]] is "field",
a. Let entry be PrivateFieldFind(P, O).
b. If entry is empty, throw a TypeError exception.
c. Return entry.[[PrivateFieldValue]].
4. Perform ? PrivateBrandCheck(O, P).
5. If P.[[Kind]] is "method",
a. Return P.[[Value]].
6. Else,
a. Assert: P.[[Kind]] is "accessor".
b. If P does not have a [[Get]] field, throw a TypeError exception.
c. Let getter be P.[[Get]].
d. Return ? Call(getter, O).
PrivateBrandCheck(O, P)
1. If O.[[PrivateBrands]] does not contain an entry e such that SameValue(e, P.[[Brand]]) is true,
a. Throw a TypeError exception.
