Return abrupt completion from IterableToList(errors)
info: |
AggregateError ( errors, message )
...
3. Let errorsList be ? IterableToList(errors).
4. Set O.[[AggregateErrors]] to errorsList.
...
6. Return O.
Runtime Semantics: IterableToList ( items [ , method ] )
1. If method is present, then
...
2. Else,
b. Let iteratorRecord be ? GetIterator(items, sync).
3. Let values be a new empty List.
4. Let next be true.
5. Repeat, while next is not false
a. Set next to ? IteratorStep(iteratorRecord).
b. If next is not false, then
i. Let nextValue be ? IteratorValue(next).
ii. Append nextValue to the end of the List values.
6. Return values.
GetIterator ( obj [ , hint [ , method ] ] )
...
3. If method is not present, then
a. If hint is async, then
...
b. Otherwise, set method to ? GetMethod(obj, @@iterator).
4. Let iterator be ? Call(method, obj).
5. If Type(iterator) is not Object, throw a TypeError exception.
6. Let nextMethod be ? GetV(iterator, "next").
...
8. Return iteratorRecord.
