<p><strong>Note:</strong> This is a low-level method, you should probably use <code><a href="/queue">.queue()</a></code> instead.</p>
<p>Every element can have one or more queues of functions attached to it by jQuery. In most applications, only one queue (called <code>fx</code>) is used. Queues allow a sequence of actions to be called on an element asynchronously, without halting program execution.</p>
<p>The <code>jQuery.queue()</code> method allows us to directly manipulate this queue of functions. Calling <code>jQuery.queue()</code> with a callback is particularly useful; it allows us to place a new function at the end of the queue.</p>
<p>Note that when adding a function with <code>jQuery.queue()</code>, we should ensure that <code>jQuery.dequeue()</code> is eventually called so that the next function in line executes.</p>
