Example wrapper + functio + document:ready + turbolinks:load

/////////////////////////////////////////////////////////
// Normal wrapper, using globals inside of it, but
// local variables and functions are not leaking out.
(function () {

  // function to execute on load
  var circle = function () {
    // do stuff
  };

  // attach to document:ready
  $(circle);

  // attach to turbolinks:load
  $(document).on('turbolinks:load', circle);

})(); // end of wrapper

/////////////////////////////////////////////////////////
// more isolated version, pass dependencies as arguments so
// compressors can optimize better the name of the variables
(function (document, $) {

  // function to execute on load
  var circle = function () {
    // do stuff
  };

  // attach to document:ready
  $(circle);

  // attach to turbolinks:load
  $(document).on('turbolinks:load', circle);

})(document, jQuery);
