title: RxJS / Angular Observables use 1 or multiple pipes?
body: <p>Having the following (just a quick example):</p>
  
  <pre><code>observable.pipe(map( s =&gt; s.anything ))
            .pipe(filter(t =&gt; t &gt; 5))
            .pipe(map( t =&gt; t+5))
            .subscribe( XXX )
  </code></pre>
  
  <p>Why should I use 1 pipe instead?</p>
  
  <pre><code>    observable.pipe(
                     map( s =&gt; s.anything ), filter(t =&gt; t &gt; 5),map( t =&gt; t+5))
                .subscribe( XXX )
  </code></pre>
  
  <p>To me, the code is more nice and readable in the first case. But no idea if that affects the behaviour anyway.</p>
