Please, I need help with my code that does not work:

this.howToUseObservables().subscribe(ress => alert('in app ' + ress));

Why testSubject.next('test'); does not fire at all? thanks

howToUseObservables(): Subject<any> {
const testSubject: Subject<any> = new Subject();
testSubject.next('test');
return testSubject;
}

this.howToUseObservables().subscribe(ress => alert('in app ' +ress));

Appears you're calling `next('test')` before subscription so it doesn't know anything about previous messages. You can try `BehaviorSubject` – yurzui Jul 12 '19 at 14:46
you are right I used BehaviorSubject instead and worked fine thanks for your help :) – Abeer Abdel-samee Jul 12 '19 at 14:52
