title: Subscribing to route params and data in Angular 2
body: <p>My form needs to access route params and data. They're observables so i need to subscribe to access their values. My question is, how do i access them both together in a single subscribe?</p>
  
  <pre><code>this._route.params.subscribe(
    params =&gt; {
      getData(params['id'], data['id2'] &lt;=== i need data value too. how do i get this???)
    });
  </code></pre>
  
  <p>Why does angular put them in 2 separate observables?</p>
