title: angular2 - service, json, how to access and remove a json element from service?
body: <p>This is how I do a get request that returns json in my service:</p>
  
  <pre><code>getModel(modelId:any){
      return this._authHttp.get(this.getModelUrl(modelId)).map(res =&gt; res.json());
  }
  </code></pre>
  
  <p>My json object looks like this {"results"=['a']}</p>
  
  <p>I am new to angular2.  How do I just return ['a']?</p>
