debounce operator with duration selector

[kwonoj]

While trying to migrate test coverage in RxJS4, could observe difference between signature of debounce operator

RxJS4

Rx.Observable.prototype.debounce(dueTime, [scheduler])
Rx.Observable.prototype.debounce(durationSelector)

while current signature only allows first one
debounce<T>(dueTime: number, scheduler: Scheduler = nextTick)

Not sure if this is intended design or not - should operator to be updated, or test coverage for latter can be dropped off?

Hmmm... I tell you what. Examine the level of complexity with supporting both on the same operator. If it incurs too many conditionals, we should probably seperate them into debounce and debounceTime

[kwonoj]

It'll also works. Just curious if it was intended.. I'll try to scope out changes and create PR based on those.

[benlesh]

Yeah... looking at this, it's probably best to rename what's there to debounceTime and add a debounce operator that takes an Observable as an argument. Likewise, we'll need to do this for throttle and throttleTime ... I'll take a look at that.

What do you think @kwonoj? Do you agree?

What's interesting is, in case of throttle it didn't had durationSelector, (https://github.com/Reactive-Extensions/RxJS/blob/master/doc/api/core/operators/throttle.md)

Rx.Observable.prototype.throttle(windowDuration, [scheduler])

only. For alignment, I think it makes sense.
