title: Javascript object literal - possible to add duplicate keys?
body: <p>In javascript, is is possible to add duplicate keys in object literal? If it is, then how could one achieve it after the object has been first created.</p>
  
  <p>For example:</p>
  
  <pre><code>exampleObject['key1'] = something;
  exampleObject['key1'] = something else;
  </code></pre>
  
  <p>How can I add the second key1 without overwriting the first key1?</p>
