Difference between `share()` and `publish().refCount()`

Question

What\'s the practical difference between observable.publish().refCount() and observable.share(). What would be an example of an scenario in which we do

Answer 1

According to article "Rxjs Observable publish refcount vs share";

With observable.publish().refCount(), once the observer completes, it will not restart if a new subscriber is added after completion. Whereas with observable.share(), if the underlying observer completes and a new subscriber is added later, the observer effectively begins a new execution and starts emitting data.
