title: Converting Object to Array using ES6 features
body: <p>Given a javascript object, how can I convert it to an array in ECMAScript-6 ?</p>
  
  <p>For example, given:</p>
  
  <pre><code> var inputObj = {a:'foo', b:[1,2,3], c:null, z:55};
  </code></pre>
  
  <p>The expected output would be:</p>
  
  <pre><code> ['foo', [1,2,3], null, 55]
  </code></pre>
  
  <p>The order of the elements in the result is not important to me.</p>
