How can I add elements to this object
<p>If I had this structure </p>

<pre><code>var data = 
{ 
    "people": [ 
      { "name" : "John", "id" : 1 },
      { "name" : "Marc", "id" : 2 }
    ] 
}
</code></pre>

<p>I want to add more elements to this, in JavaScript, specifically in jQuery to then send it like this</p>

<pre><code>var dataString = JSON.stringify(data);
$.post('some.php', { data: dataString}, showResult, "text");
</code></pre>
