title: How to get specific object values from all child location in firebase
body: <p>In firebase</p>
  
  <pre><code>var userRef = http://xx.firebaseio.com/users
  </code></pre>
  
  <p>I can get all the users like </p>
  
  <p>var userAllRecords = $firebase(userRef).$asObject();</p>
  
  <p>and this will give me all the records and I can filter them and get desire values/operations.</p>
  
  <p>But How can I avoid this extra operations specially while working on mobile device apps when I am only interested in one set of records say users balance and name from all users?</p>
  
  <p>So I am looking something like by passing object names in asObject() method. e.g only get user_balance and user_name from all users</p>
  
  <p>e.g: var userAllRecords = $firebase(userRef).$asObject(user_balance, user_name);</p>
