| Explicit iterator closing in response to error |
| esid: sec-promise.any |
| info: | |
| 5. Let result be PerformPromiseAny(iteratorRecord, C, promiseCapability). |
| 6. If result is an abrupt completion, then |
| a. If iteratorRecord.[[Done]] is false, set result to IteratorClose(iteratorRecord, result). |
| b. IfAbruptRejectPromise(result, promiseCapability). |
| |
| Runtime Semantics: PerformPromiseAny |
| |
| 8. Repeat |
| ... |
| i. Let nextPromise be ? Call(promiseResolve, constructor, « nextValue »). |
| flags: [async] |
| features: [Promise.any, Symbol.iterator, computed-property-names, Symbol, arrow-function] |
