What is the difference in two expressions in angular?

Question

JavaScript

I saw such an example in the dock, and I can’t understand why wrap everything in an array and pass the first two elements, which are then passed to the function parameters if it works without it:

// Пример из доки
app.controller('authCtrl', ['$rootScope', '$location', function($rootScope, $location) {
  // Код
}]);
// Мой пример
app.controller('authCtrl', function($rootScope, $location) {
  // Код
});

Answer 1

The first option will work everywhere.
The second option, if $inject is not used, will break after minification.
That's it in a nutshell =)
