Answer 1

In your TS logic, define an observable based on an "interval", which will emit the values 0, 1, 2, 3, 4, 0, 1, ...

this.index = Observable.interval(10000).map(n => n % this.array.length);

In your component, unwrap that observable using async and use it to index into the array.

{{array[index | async]}}
