angularjs - Is there any performance difference between $emit event and casual function call in ng-click? -

- 

<script>   angular.app('app', [])   .controller('ctrl', function($scope) {      $scope.$on('foo', function(evt, msg) {          alert(msg);       });      $scope.foo = function(msg) {           alert(msg);       };     }); </script> <div ng-app="app"> <div ng-controller="ctrl"> <button ng-click="foo('some msg')">call</button> <button ng-click="$emit('foo')">emit</button> </div> </div>

is there significant performance different between 2 cases? case should go by?

i have been playing around irb , have string looks this: irb(main):072:0> puts ["[\"4354 5432 5432 xxxxx\", \"6547 6547 8543 xxxxx\", \"2344 6543 6674 xxxxx\", \"2346 6236 7543 xxxxx\", \"1273 5585 5587 xxxxx\"]"] => nil irb(main):073:0> what want gsub last 2 "x" s of each 17 digit combination, 23 . what i've tried far (i've been using rubular): a.gsub(/\d[x]/,"23") <= grabs "x" s i'm close a.gsub(/\w[x{2}]/,"23") <= grabs "x" s grabs two digits each combination. is there easier way i'm not understanding? a.gsub(/\d{4} \d{4} \d{4} xxx\kxx/, '23') \d{4} = 4 digits what \k drop matched far. can use don't replace entire number, still able validate have in desired format.
