Adding a callback handler to a jQuery plugin

When you're creating a plugin sometimes you'll have to deal with callbacks, and there is a lot of ways to do it, and here I show you one of these :

(function($){
  $.fn.myAwesomePlugin = function(settings) {
    var callback = settings.callback;
    if ($.isFunction(callback)) {
      var parameter = 'Hello World';
      callback.call(this, parameter);
    }
  };
})(jQuery);

And then when you call your plugin, it would be looking like this:

$("#a-random-element").myAwesomePlugin({
  callback: function(data){
    alert(data);
  }
});
