    I just modified your js fiddle. Please check the fiddle example

    function personController($scope) {
    $scope.firstName= "John";
    $scope.lastName= "Doe";
}

    There was no issue with your code except JS fiddle settings from onLoad to No wrap - in head

    Same problrm may be if you will try to nest ngApp into anothe ngApp.

    The documentation says:

    AngularJS applications cannot be nested within each other.

    You have to input function as a parameter inside module

    var app = angular.module('app',[]);
app.controller('personController',function($scope){
  $scope.firstName = 'John';
  $scope.lastName = 'Smith';
});

    You need to create an application module, and then add a controller to it. In angular it is all about dependencies. Secondly you need an app-name. The base tutorial is on their main page: https://docs.angularjs.org/tutorial/step_00 I started with it, and it worked fine with me. Just do all steps starting from step 1.

    It is a new approach. We cannot use controllers without a module no more. Have a look at this. Just add a module and append the controller then you will have no problem.
