title: Angular 8 Observable.interval changed?
body: <p>I am trying to use Observable.interval on angular 8 and it doesn't seem to like it.</p>
  
  <p>First I import rxjs:</p>
  
  <pre><code>import { Observable } from 'rxjs';
  </code></pre>
  
  <p>Then the code:</p>
  
  <pre><code>Observable.interval(1000).subscribe(x =&gt; {
      // something
    });
  </code></pre>
  
  <p>What is the angular 8 syntax?</p>
