description: >
Checks the behavior of Abstract Operation StringListFromIterable
called by Intl.ListFormat.prototype.formatToParts().
info: |
StringListFromIterable
1. If iterable is undefined, then
a. Return a new empty List.
2. Let iteratorRecord be ? GetIterator(iterable).
3. Let list 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. If Type(nextValue) is not String, then
1. Let error be ThrowCompletion(a newly created TypeError object).
2. Return ? IteratorClose(iteratorRecord, error).
iii. Append nextValue to the end of the List list.
6. Return list.
