app.controller('myCtrl', function($scope) {
$scope.firstName= "John";
$scope.lastName= "Doe";
});

Explication

The ng-controller="myCtrl" attribute is an AngularJS directive. It defines a controller.

The myCtrl function is a JavaScript function.

AngularJS will invoke the controller with a $scope object.

In AngularJS, $scope is the application object (the owner of application variables and functions).

The controller creates two properties (variables) in the scope (firstName and lastName).

The ng-model directives bind the input fields to the controller properties (firstName and lastName).

AngularJS Controller
app.controller('myCtrl', function($scope) {
$scope.firstName= "John";
$scope.lastName= "Doe";
});
