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).
