RXJS Wait for all observables in an array to complete (or error)

Question

I\'m pushing observables into an array like such...

var tasks$ = [];
tasks$.push(Observable.timer(1000));
tasks$.push(Observable.timer(3000));
tasks$.push(Ob         


        

Answer 1

For me this sample was best solution.

const source = Observable.interval(500);
const example = source.sample(Observable.interval(2000));
const subscribe = example.subscribe(val => console.log('sample', val));

So.. only when second (example) emit - you will see last emited value of first (source).

In my task, I wait form validation and other DOM event.
