|
1. Let list be an empty List.
|
||
|
|
2. Let spreadRef be the result of evaluating AssignmentExpression.
|
||
|
|
3. Let spreadObj be GetValue(spreadRef).
|
||
|
|
4. Let iterator be GetIterator(spreadObj).
|
||
|
|
5. ReturnIfAbrupt(iterator).
|
||
|
|
6. Repeat
|
||
|
|
a. Let next be IteratorStep(iterator).
|
||
|
|
b. ReturnIfAbrupt(next).
|
||
|
|
c. If next is false, return list.
|
||
|
|
d. Let nextArg be IteratorValue(next).
|
||
|
|
e. ReturnIfAbrupt(nextArg).
|
||
|
