title: NgRX store.select returns store object instead of observable object
body: <p>I have written a short example of Ngrx. I had no idea why this short code could not run properly.</p>
  
  <pre><code>constructor(private store: Store&lt;CounterState&gt;){
  this.counter = store.select('counter');
  console.log(this.counter);
  }
  </code></pre>
  
  <p>This piece of code prints a Store object to the console instead of an observable. It is weird.
  The full version of the app please follow the link below.
