| Iterator is not closed when the "resolve" capability returns an abrupt |
| completion. |
| info: | |
| ... |
| 3. Let promiseCapability be ? NewPromiseCapability(C). |
| ... |
| 6. Let result be PerformPromiseAllSettled(iteratorRecord, C, promiseCapability). |
| 7. If result is an abrupt completion, then |
| a. If iteratorRecord.[[Done]] is false, set result to IteratorClose(iteratorRecord, result). |
| b. IfAbruptRejectPromise(result, promiseCapability). |
| 8. Return Completion(result). |
| |
| Runtime Semantics: PerformPromiseAllSettled |
| |
| ... |
| 6. Repeat |
| ... |
| d. If next is false, then |
| ... |
| iii. If remainingElementsCount.[[Value]] is 0, then |
| 1. Let valuesArray be CreateArrayFromList(values). |
| 2. Perform ? Call(resultCapability.[[Resolve]], undefined, « valuesArray »). |
| |
| IfAbruptRejectPromise |
| |
| 1. IfAbruptRejectPromise(value, capability). |
