Description

[Sankha Narayan Guria [:sankha]]

This is a follow up of bug 869996.

Quoting Rick's comments in bug 869996, the spec had been changed for the iterator methods of Set.

> Please see 15.16.6.2.2 SetIterator.prototype.next() of the latest
> specification draft.
> 
> .next() should produce an ItrResult object that has both a "value" and
> "done" property. The "value" property's own value will be as those shown
> above, the "done" property will be a boolean value that is |true| until
> there are no more values to yield, at which time it will have the boolean
> value |false|
> 
> See line 14 comments, StopIteration has been removed from the design of the
> feature

This actually applies to:

ArrayIterator.prototype.next()
MapIterator.prototype.next()
SetIterator.prototype.next()

I think this has been done for MapIterator and SetIterator objects? Wingo can you confirm?

Then I'll make the changes accordingly in bug 894658 for ArrayIterator methods.

For documentation purpose, in which release (and if possible in which bug to be able to access info in it).

This was done in bug 907077 for Sets, Maps and bug 919948 for the Array Iterators.
