Why do angularjs controller declaration have this syntax structure?

Question

I see the following angularjs controller syntax structure all the time.

angular.module(\'7minWorkout\').controller(\'WorkoutController\', 
[\'$scope\', \'$in         


        

Answer 1

or you can use following syntax, according to popular angular-styleguide https://github.com/johnpapa/angular-styleguide

angular.module('7minWorkout')
       .controller('WorkoutController', WorkoutController);
WorkoutController.$inject = ['$scope', '$interval', '$location'];

function WorkoutController($scope, $interval, $location) {

}
