[jQuery] $(function()

[Danjojo]

2 Questions.

1. are there the correct number of parenthesis in this code. Is there
a syntax error? It runs fine..

2. What is this idea of wrapping the code in like a blank function()
with no name? The one the looks like $function() ? I don't understand
it and I want to. Being a noob javascript coder I understand functions
like:

function myCall() {
 // etc
}


$(function() {
        $("#languages").bind('change', function() {
                var country = $(this).val();
                if(country) {
                        $('#countryFlag').attr("src", "images/" + country + 
".gif");
                        $.cookie('language', country, {expires: 7}); // set 
cookie
                }
        });
});
