title: Access this object's name
body: <p>I'm attempting to "loop" through an object and grab the name if a certain test passes.</p>
  
  <p>For instance</p>
  
  <pre><code>var x = {
   'first':[
          'ab',
          'abc',
   ],
   'second':[
          'sia',
          'sss'
   ],
   'third':[
          'jp',
          'jh'
   ]
  };
  </code></pre>
  
  <p>As you can see, I have an object containing arrays.</p>
  
  <p>Let's say that I am given the value "sss" .... I am trying to figure out how to get Javascript to output "second" when given the appropriate value.</p>
  
  <p>The same goes for the following scenarios</p>
  
  <pre><code>third for jp
  third for jh
  first for abc
  </code></pre>
  
  <p>and so on.</p>
