Angular controller not register to module

Question

I am still new on angularjs and have a question: How does the controller still know which module it registerred to on code snippet below (found on the Angular official document): JS

 angular.module('App', []);
    function Ctrl($scope) {
      $scope.val = 1234.56789;
    }

Html something like:

<html ng-app="App">
<body>
<div ng-controller="Ctrl">
 ........
</div>
</body>
</html>

I suspect there is something to do with bootstrap time and $scope available globally???

Thank you very much

If you want to define a controller in a module, call the controller method on the module:

var module = angular.module('App', []);

module.controller('Ctrl', function ($scope) {
   $scope.val = 1234.56789;
});

it works because it defines a simple controller in a global window context... but in a real world, I suppose you can't find an application which is this simple
