title: Using a selectors value in a component
body: <p>When using a selector is there any way possible to access a property of the observable without subscribing to it? For example: </p>
  
  <pre><code>public selectedOrder$ = this.store.select(fromRoot.getSelectedOrder);
  </code></pre>
  
  <p>Above is the selector I have. Later in my code, I am trying to access a property of that selector like below: </p>
  
  <pre><code>ngOnInit() {
    this.routerUrl$.pipe(map(x =&gt; {
    switch (x) {
      case ('/dashboard/order/' + this.selectedOrder$.orderNumber):
      omitted code...
  </code></pre>
  
  <p>Is there a similar operator that I could use to set a variable equal to selectedOrder$.orderNumber or any other way to access this property in the code only (Note: I am not needing this in the template). </p>
