+description: PrivateBrandCheck fails when the object O doesn't have P.[[Brand]] (private getter)
+esid: sec-privatefieldget
+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.
