jQuery, Javascript : Javascript wrapped in jQuery(), $() - what does it mean?
<p>I'm having trouble understanding a type of jQuery selection, and I hope someone can explain it to me in clear terms.</p>

<p>It's taken from <a href="http://stackoverflow.com/questions/7193425/how-do-you-animate-fb-canvas-scrollto">this Stack Overflow question</a>.</p>

<p>Basically, it has the common jQuery: <code>$( selector )</code>.</p>

<p>But inside that it has <code>$({ y: iFrameScrollY })</code>.</p>

<p>I've never seen this before. <strong>What does it mean to have <code>{ ... }</code> and <code>someVal: anotherVal</code> inside the brackets?</strong></p>

<p><em>Also, please recommend a different title for this question, to make it easier for others to find it.</em></p>
