| description: Class construction should error if evaluation of field initializer errors |
| esid: sec-ecmascript-function-objects-construct-argumentslist-newtarget |
| info: | |
| [[Construct]] ( argumentsList, newTarget) |
| ... |
| 8. If kind is "base", then |
| a. Perform OrdinaryCallBindThis(F, calleeContext, thisArgument). |
| b. Let result be InitializeInstanceFields(thisArgument, F). |
| c. If result is an abrupt completion, then |
| i. Remove calleeContext from execution context stack and restore callerContext as the running execution context. |
| ii. Return Completion(result). |
| |
| 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). |
