12.3.6.1 Runtime Semantics: ArgumentListEvaluation
|
|
|
|
ArgumentList : ArgumentList , ... AssignmentExpression

|
|
|
1. Let precedingArgs be the result of evaluating ArgumentList.
|
|
2. Let spreadRef be the result of evaluating AssignmentExpression.
|
|
3. Let iterator be GetIterator(GetValue(spreadRef) ).

4. ReturnIfAbrupt(iterator).

7.4.4 IteratorValue ( iterResult )
|
|
|
|
1. Assert: Type(iterResult) is Object.
|
|
2. Return Get(iterResult, "value").
