| Set ( [ iterable ] ) |
| |
| When the Set function is called with optional argument iterable the following steps are taken: |
| |
| ... |
| 7. Else, |
| a. Let adder be Get(set, "add"). |
| b. ReturnIfAbrupt(adder). |
| c. If IsCallable(adder) is false, throw a TypeError exception. |
| d. Let iter be GetIterator(iterable). |
| e. ReturnIfAbrupt(iter). |
| ... |
| 9. Repeat |
| a. Let next be IteratorStep(iter). |
| b. ReturnIfAbrupt(next). |
| c. If next is false, return set. |
| d. Let nextValue be IteratorValue(next). |
| e. ReturnIfAbrupt(nextValue). |
| f. Let status be Call(adder, set, «nextValue.[[value]]»). |
| g. If status is an abrupt completion, return IteratorClose(iter, status). |
