1. Let spreadRef be the result of evaluating AssignmentExpression.
|
|
2. Let spreadObj be ? GetValue(spreadRef).
|
|
3. Let iterator be ? GetIterator(spreadObj).
|
|
4. Repeat
|
|
a. Let next be ? IteratorStep(iterator).
|
|
b. If next is false, return nextIndex.
|
|
c. Let nextValue be ? IteratorValue(next).
|
|
d. Let status be CreateDataProperty(array, ToString(ToUint32(nextIndex)),
|
|
nextValue).
|
|
e. Assert: status is true.
|
|
f. Let nextIndex be nextIndex + 1.
