  Old  jQuery function confusion

Ok as i've been going through this book i'm learning about basic functions.

I know that this is the basic format for a function.

function functionName() {
$("p").fadeOut("slow");
}

Then you'll have a button to call it out.

But i'm reading about Creating new HTML Elements and in the explample, why is the function set ou tlike this.

$(function()
{
$("<p>Test</p>")
.insertAfter("#first");
});

Just wondering, what is with the $function() could someone please explain, thanks.

It is a matter of timing, normal JS functions run before the HTML is ready to be messed with. When it is in there jQuery waits until everything is good to go.

Code:
$(function(){
});
Is short hand for

Code:
jQuery(document).ready(function(){
});
What the ready method does, succinctly, is use cross-browse compatible methods to ensure that the element you've specified has been loaded fully and is in a "ready" state to be manipulate. We choose to the document element because it represents the whole of the page we're working with.
