title: Unset people property using mixpanel JavaScript client
body: <p>I try to remove a property for a user using mixpanel JavaScript API. As I can see, there is only a method set, but no method unset. I tried to set the property with undefined or null but when I do so, the property still exists with no value. I would like to totally remove it as we can do it with the mixpanel interface. Is that possible?</p>
  
  <p>Thanks for your help!</p>
  
  <p>Some code:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>// Let set the property 'foo' with a value 'bar' to the current user
  mixpanel.people.set("foo", "bar");
  
  // Now, let unset this proprety
  // Oops, there is no method unset...
  // Let's try something else
  mixpanel.people.set("foo"); // nop...
  mixpanel.people.set("foo", undefined); // nop...
  mixpanel.people.set("foo", null); // the value is now empty but the property still exists</code></pre>
  </div>
  </div>
  </p>
