javascript - Are $(function(){}); and $("document").ready(function(){}); the same?

Question

I've been enjoying Lynda.com's Jquery Essential Training, and I've noticed that in the beginning the instructor uses:

    Fig. 1

    $("document").ready(function(){
    fun stuff goes here
    });

However, somewhere along the line he starts using:

    Fig. 2

    $(function(){
    fun stuff goes here
    });

From the way he speaks, it sounds as if they are completely synonymous (some inherent jquery shorthand?) but as far as I can tell, it's never explicitly touched upon.

I'm sure someone could clear this up quickly for me. I found this but I believe that question is slightly different--I understand the concept of calling a function on document ready versus one that is globally available; (those functions also have names.)

The instructor uses phantom functions (I think that was the term for a function without a name,) and when typing out Fig. 2, he says "So this will be on document ready..."

Answer 1

Yes, they are exactly the same, just aliases.

From the jQuery site:

All three of the following syntaxes are equivalent:

$(document).ready(handler)
$().ready(handler) (this is not recommended)
$(handler)
