Set ( [ iterable ] )
|
|
|
|
When the Set function is called with optional argument iterable the following steps are taken:
|
|
|
|
...
|
|
5. If iterable is not present, let iterable be undefined.
|
|
6. If iterable is either undefined or null, let iter be undefined.
|
|
...
|
|
8. If iter is undefined, return set.
