Troubleshooting: Angular.js Functionality Failing to Execute in Plunker

Could you please review This Plunker Demo and provide insights on why it is not functioning correctly?

Below is the code snippet I am using:

<!DOCTYPE html>
<html ng-app>

  <head>
    <script data-require="<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a7c6c9c0d2cbc6d589cdd4e795899789978ac6cbd7cfc6899496">[email protected]</a>" data-semver="2.0.0-alpha.31" src="https://code.angularjs.org/2.0.0-alpha.31/angular.js"></script>
    <link rel="stylesheet" href="style.css" />
    <script src="script.js"></script>
  </head>

  <body>
    <div ng-controller="FirstController">
      <h1>{{msg}}</h1>
    </div>
  </body>

</html>

The content of script.js is as follows:

var FirstController = function($scope){
    $scope.msg = "This Must Work!";
};

Are you considering using Angular or Angular 2 for your project? Currently, Angular 2 is still in beta and may not be the most commonly used version.

If you opt for Angular 1, there are a few key things to keep in mind:

Firstly, ensure that you declare the app in your JavaScript code. This can be done by writing something similar to this:

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

Additionally, when using the ng-app directive, make sure to provide it with the same value as the 'module' you created earlier (e.g., myApp):

<html ng-app="myApp">

To utilize a controller within your app, you need to associate it with your app so that Angular recognizes its presence. This can be achieved through the following method:

myApp.controller('FirstController', ['$scope', function($scope) {
  $scope.msg = 'This Must Work!';
}]);

In this example, I have also utilized the Angular CDN.

The linked angular file (https://code.angularjs.org/2.0.0-alpha.31/angular.js) seems to be corrupted, preventing Angular from loading properly.

The current reference to Angular that you are utilizing is invalid. I made adjustments to the code by implementing a valid Angular reference, and now everything is functioning correctly. Additionally, it seems like you are not properly setting up the controller. The correct process involves first creating a module and then adding a controller to it. Here is how the "script.js" file should be structured:

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

app.controller('FirstController', function($scope) {
    $scope.msg = "This Should Work!";
});

Here is the updated HTML with the valid Angular reference included:

<!DOCTYPE html>
<html>

<head>
    <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
    <link rel="stylesheet" href="style.css" />
    <script src= "script.js"></script>
</head>

<body>
    <div ng-app="myApp" ng-controller="FirstController">  
       <h1>{{msg}}</h1>
    </div>
</body>

</html>

I also added ng-app="myApp" to establish a connection to the created module. Hopefully, this clarifies things for you.
