This is a way of interacting with the injector (one of several). The string
literal containing ‘$scope’ tells the injector that the parameter at index 0
(first item in the array) should be ‘$scope’ from the injector. ‘$scope’ isn’t
registered globally in the injector, it comes from locals (so, if you
instantiate a controller via the $controller service, you can supply injector
locals via the second parameter, `$controller(‘ctrlName’, { $scope: myScope
});`.
There are a few ways to use the injector:
```
// One example:
MyController.$inject = [‘$scope’, ‘$http’];
function MyController($scope, $http) {
// ...
}
angular.controller(“MyController”, MyController);
// The example you provided:
angular.controller(“MyController”, [“$scope”, “$http”, function($scope, $http) {
// ...
}]);
// The third method is discouraged, because it requires parsing
`function.toString()`, and this
// does not work as expected when code is minified.
angular.module(“MyController”, function($scope, $http) {
// ...
});
```
These rules apply to everything that the injector deals with, from directives
to services to filters to controllers.
If that didn’t clear things up, feel free to ask for clarification =)
