| Promise is rejected when the "resolve" capability returns an abrupt |
| completion. |
| info: | |
| 1. Let C be the this value. |
| [...] |
| 3. Let promiseCapability be ? NewPromiseCapability(C). |
| [...] |
| 7. Let result be PerformPromiseAll(iteratorRecord, C, promiseCapability). |
| 8. If result is an abrupt completion, then |
| a. If iteratorRecord.[[Done]] is false, let result be |
| IteratorClose(iterator, result). |
| b. IfAbruptRejectPromise(result, promiseCapability). |
| |
| 25.4.4.1.1 Runtime Semantics: PerformPromiseAll |
| |
| [...] |
| 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 »). |
| |
| 25.4.1.1.1 IfAbruptRejectPromise |
| |
| IfAbruptRejectPromise is a short hand for a sequence of algorithm steps that |
| use a PromiseCapability Record. An algorithm step of the form: |
| |
| 1. IfAbruptRejectPromise(value, capability). |
| |
| means the same thing as: |
| |
| 1. If value is an abrupt completion, then |
| a. Perform ? Call(capability.[[Reject]], undefined, « value.[[Value]] »). |
| b. Return capability.[[Promise]]. |
| 2. Else if value is a Completion Record, let value be value.[[Value]]. |
