| description: Class construction should error if evaluation of field initializer in super errors |
| esid: sec-super-keyword-runtime-semantics-evaluation |
| info: | |
| Runtime Semantics: Evaluation |
| SuperCall : superArguments |
| 1. Let newTarget be GetNewTarget(). |
| 2. If newTarget is undefined, throw a ReferenceError exception. |
| 3. Let func be ? GetSuperConstructor(). |
| 4. Let argList be ArgumentListEvaluation of Arguments. |
| 5. ReturnIfAbrupt(argList). |
| 6. Let result be ? Construct(func, argList, newTarget). |
| 7. Let thisER be GetThisEnvironment( ). |
| 8. Let F be thisER.[[FunctionObject]]. |
| 9. Assert: F is an ECMAScript function object. |
| 10. Perform ? InitializeInstanceFields(result, F). |
| |
| InitializeInstanceFields ( O, constructor ) |
| 1. Assert: Type ( O ) is Object. |
| 2. Assert: Assert constructor is an ECMAScript function object. |
| 3. Let fieldRecords be the value of constructor's [[Fields]] internal slot. |
| 4. For each item fieldRecord in order from fieldRecords, |
| a. If fieldRecord.[[static]] is false, then |
| i. Perform ? DefineField(O, fieldRecord). |
| |
| DefineField(receiver, fieldRecord) |
| 1. Assert: Type(receiver) is Object. |
| 2. Assert: fieldRecord is a Record as created by ClassFieldDefinitionEvaluation. |
| 3. Let fieldName be fieldRecord.[[Name]]. |
| 4. Let initializer be fieldRecord.[[Initializer]]. |
| 5. If initializer is not empty, then |
| a.Let initValue be ? Call(initializer, receiver). |
