  10. Perform ! CreateDataProperty(obj, "status", "fulfilled").
  11. Perform ! CreateDataProperty(obj, "value", x).
  12. Set values[index] to be obj.

  14. If remainingElementsCount.[[Value]] is 0, then
    a. Let valuesArray be ! CreateArrayFromList(values).
    b. Return ? Call(promiseCapability.[[Resolve]], undefined, « valuesArray »).

  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 »).
