Multi-casting is the practice of broadcasting to a list of multiple subscribers in a single execution. Let’s demonstrate the multi-casting feature,


var source = Rx.Observable.from([1, 2, 3]);
var subject = new Rx.Subject();
var multicasted = source.multicast(subject);
// These are, under the hood, `subject.subscribe({...})`:
multicasted.subscribe({ next: (v) => console.log('observerA: ' + v) });
multicasted.subscribe({ next: (v) => console.log('observerB: ' + v) });
