description: Rejecting through deferred invocation of the provided resolving function
esid: sec-promise.allsettled
info: |
6. Let result be PerformPromiseAllSettled(iteratorRecord, C, promiseCapability).
Runtime Semantics: PerformPromiseAllSettled
6. Repeat
...
z. Perform ? Invoke(nextPromise, "then", « resolveElement, rejectElement »).
Promise.allSettled Reject Element Functions
9. Let obj be ! ObjectCreate(%ObjectPrototype%).
10. Perform ! CreateDataProperty(obj, "status", "rejected").
11. Perform ! CreateDataProperty(obj, "reason", x).
12. Set values[index] to be obj.
13. Set remainingElementsCount.[[Value]] to remainingElementsCount.[[Value]] - 1.
14. If remainingElementsCount.[[Value]] is 0, then
a. Let valuesArray be CreateArrayFromList(values).
b. Return ? Call(promiseCapability.[[Resolve]], undefined, « valuesArray »).
