description: >
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]].
