| ii. Set remainingElementsCount.[[value]] to remainingElementsCount.[[value]] − 1. |
| iii. If remainingElementsCount.[[value]] is 0, |
| 1. Let error be a newly created AggregateError object. |
| 2. Perform ! DefinePropertyOrThrow(error, "errors", Property Descriptor { [[Configurable]]: true, [[Enumerable]]: false, [[Writable]]: true, [[Value]]: errors }). |
| 3. Return ThrowCompletion(error). |

| Promise.any Reject Element Functions |

| Let alreadyCalled be the value of F's [[AlreadyCalled]] internal slot. |
| If alreadyCalled.[[value]] is true, return undefined. |
