Different ways of saying document ready in jQuery?

Question

Are these both the same thing, i.e. ways of saying document ready:

$(function() {
  //
});

and

$(function($) {
   //
})(jQ         


        

Answer 1

This one is incorrect:

$(function($) {
   //
})(jQuery);

You're passing a function to $(...), then calling the result. However, the result of $(...) is a jQuery object, which is not a function. You might see it better this way:

$(

    function($) {
        //
    }

)

(jQuery);

Generally, there are three versions of document.ready, which are all equal to each other:

$(function() {...});

$(document).ready(function() {...});

$().ready(function() {...});
