I am new in Angularjs javascript. Tell me what is difference between below code:-

app.controller("firstController", ['$scope', '$modal', '$log', 'HttpService', 'FisrtSharedService', 'SecondSharedService', function($scope, $modal, $log, HttpService, FisrtSharedService, SecondSharedService) {

}]);

app.controller("firstController", function($scope, $modal, $log, HttpService, FisrtSharedService, SecondSharedService){

});

Whether both are same or different? and why? Thanks in advance.

No functional difference. The one using [] is to allow a minified version to be read correctly. –  Zack Argyle Nov 6 at 5:35

It's used when you minified JS files. '$scope', '$modal', '$log', 'HttpService', 'FisrtSharedService', 'SecondSharedService' just declares injectors. 

app.controller("firstController", ['$scope', '$modal', '$log', 'HttpService',    'FisrtSharedService', 'SecondSharedService', function($scope, $modal, $log, HttpService, FisrtSharedService, SecondSharedService) {

}]);

You also declare injectors like this: 

firstController.$inject = ['$scope', '$modal', '$log', 'HttpService',    'FisrtSharedService', 'SecondSharedService'];
app.controller("firstController", function($scope, $modal, $log, HttpService,  FisrtSharedService, SecondSharedService){

});
