What is the difference between $(document).ready(function() and $(function() ?

Question

So I know what this does:

$(document).ready(function(){
    // Your code here...
});

Now I have seen people doing this lately:

Answer 1

yes, they're doing the same thing. the $() function wraps $(document).ready() when the parameter to the call is a single function object.
