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).
