Error when accessing an iterator result's `value` property (rejecting
|
|
promise)
|
|
info: |
|
|
Let result be PerformPromiseAny(iteratorRecord, C, promiseCapability).
|
|
If result is an abrupt completion, then
|
|
If iteratorRecord.[[Done]] is false, set result to IteratorClose(iteratorRecord, result).
|
|
IfAbruptRejectPromise(result, promiseCapability).
|
|
|
|
...
|
|
|
|
Runtime Semantics: PerformPromiseAny
|
|
|
|
...
|
|
Repeat
|
|
Let nextValue be IteratorValue(next).
|
|
If nextValue is an abrupt completion, set iteratorRecord.[[Done]] to true.
|
|
ReturnIfAbrupt(nextValue).
