  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.
