So, this is kind of a nasty pattern - keeping two data structures around
when one will suffice, as there's the problem of these getting out of sync
if code changes in the future.
Then I looked at channel.join. :-)
join: function (h, c) {
var i = c.length;
var len = i;
var f = function() {
if (!(--i)) h();
};
for (var j=0; j<len; j++) {
!c[j].fired?c[j].subscribeOnce(f):i--;
}
if (!i) h();
},
Yikes! Not terribly understandable, especially since it's not immediately
obvious how a method like join() should work in the first place. But the
good news is, I think we could go to a single "map" and not use the array,
since it doesn't need to be an array. We can change the for loop to a for
(var key in map) loop, and then reference c[key] in the body of the loop
instead.
Issues?
