1. Let status be the result of performing IteratorBindingInitialization for
|
|
FormalsList using iteratorRecord and environment as the arguments.
|
|
2. ReturnIfAbrupt(status).
|
|
3. Return the result of performing IteratorBindingInitialization for
|
|
FormalParameter using iteratorRecord and environment as the arguments.
