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.
