difference between responeJSON and $.parseJSON
<p>Okay so when I usually work with JSON I collect data like this:</p>

<pre><code>&lt;?php 
    $some_array = array("success" =&gt; "The upload is successful", "failed" =&gt; "The upload has failed");
    echo  json_encode($some_array);
?&gt;
</code></pre>



<pre><code>&lt;script type="text/javascript"&gt;
    success: function(data){
        var imported = $.parseJSON(data);
        ...
    }
&lt;/script&gt;
</code></pre>

<p>but I I'm currently trying to figure a jquery plugin that uses responseJSON and I'm not sure how to use it:</p>

<pre><code>onComplete: function(id, fileName, responseJSON) {
    if (responseJSON.success) {
</code></pre>

<p>How does this work?</p>
