JQuery, new JS function syntax

Question

Can someone explain me the syntax below line 1? I am OK with js and function references, but this code looks a bit confusing. E.g. is it function declaration and execution?

jQuery.noConflict();
(function($) { 
  $(function() {
    // more code using $ as alias to jQuery
  });
})(jQuery);
// other code using $ as an alias to the other library

Answer 1

Exactly.
You create an anonymous function which takes one parameter, and immediately invoke it with the parameter jQuery.
