bracket in directive definition

[lewis500]

Hi, I was curious why the directive snippet has an array like directive('', ['', function(){... when the documentation and most examples I've seen just have directive( " , function(){ ?

Hi Lewis,

It's for dependency injection, more info can be found here http://docs.angularjs.org/guide/di

Example from link:

angular.module('myModule', []).
  config(['depProvider', function(depProvider){
    ...
  }]).
  factory('serviceId', ['depService', function(depService) {
    ...
  }]).
  directive('directiveName', ['depService', function(depService) {
    ...
  }]).
  filter('filterName', ['depService', function(depService) {
    ...
  }]).
  run(['depService', function(depService) {
    ...
  }]);
