     13    1. Let spreadRef be the result of evaluating AssignmentExpression.
     14    2. Let spreadObj be ? GetValue(spreadRef).
     15    3. Let iterator be ? GetIterator(spreadObj).
     16    4. Repeat
     17       a. Let next be ? IteratorStep(iterator).
     18       b. If next is false, return nextIndex.
     19       c. Let nextValue be ? IteratorValue(next).
     20       d. Let status be CreateDataProperty(array, ToString(ToUint32(nextIndex)),
     21          nextValue).
     22       e. Assert: status is true.
     23       f. Let nextIndex be nextIndex + 1.
