jQuery (document).ready(function($)
<p>I wrote a jQuery script (below) and I used the (document).ready(function($)) function
does it slow down the website, and if it does than can you please show me a way to create such functions without slowing down the site?
Thank you very much!</p>

<pre><code>&lt;script&gt;
jQuery(document).ready(function($){ 
    $('#columns').wrapInner('&lt;div id="columnsInner" /&gt;');
    $("div.productInfo:first").wrap("&lt;div id='productDetails' /&gt;"); 
});
&lt;/script&gt;
</code></pre>
