33. Let result be InitializeStaticFields(F).
|
|
34. If result is an abrupt completion, then
|
|
a. Set the running execution context's LexicalEnvironment to lex.
|
|
b. Return Completion(result).

InitializeStaticFields(F)
|
|
1. Assert: Type(F) is Object.
|
|
2. Assert: F is an ECMAScript function object.
|
|
3. Let fieldRecords be the value of F's [[Fields]] internal slot.
|
|
4. For each item fieldRecord in order from fieldRecords,
|
|
a. If fieldRecord.[[static]] is true, then
|
|
i. Perform ? DefineField(F, 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).
