title: Select the first JSON array child value
body: <p>I want to get the value that holds the first child of a JSON array.</p>
  
  <p>This is the array :</p>
  
  <pre><code>var sms = {
      '1' : {
          'address' : '+123',
          'body' : 'SMS1'
      },
      '2' : {
          'address' : '+123',
          'body' : 'SMS2'
      },
      '3' : {
          'address' : '+123',
          'body' : 'SMS3'
      },
      '4' : {
          'address' : '+123',
          'body' : 'SMS4'
      }
  };
  </code></pre>
  
  <p>The reason is i want to loop in it to search a string using the first childs
  value as it is above. Example sms.[0] = 1;</p>
