| 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). |
| |
