How can I remove a property from an object? : <p>I have this object:</p>

<pre><code>  {"wordFormId":"abandon",
   "wordFormIdentity":1,
   "ascii":97,
   "wordId":"abandon",
   "primary":true,
   "posId":2}
</code></pre>

<p>How can I remove the ascii property? I know I could set it to null but I assume it would then still be there. What I would like to do is to completely remove it.</p>
