title: Retrieve single JSON element in an JSON object in angular 2
body: <p>I have a JSON  as </p>
  
  <pre><code>   labelnames={
      "one": "",
      "two": "",
      "three": "",
      "four": ""
  };
  </code></pre>
  
  <p>Now i have separate condition for each <code>labelname</code>. So, if i wish to display <code>labelname[0]</code> i.e., "one" and use it, then what is the way i should follow?</p>
  
  <p>I tried using pipes and ngfor loop, but i am getting all values in labelnames</p>
  
  <pre><code> &lt;li *ngFor="let doc of labelnames | keys"&gt;
   {‌{doc.key}}
  &lt;/li&gt;
  </code></pre>
  
  <p>I just need single element depending on index.</p>
  
  <p>Help me in solving this.</p>
