Javascript iife angularjs example

Question

I have a simple controller which works absolutely fine.

var myApp = angular.module('myApp', []);
myApp.controller('ProductController', ['$scope', function ($scope) {
$scope.Message = "Hello World";
} ]);

However, if I want to put this inside a function, i.e.

(function () { 
var myApp = angular.module('myApp', []);
myApp.controller('ProductController', ['$scope', function ($scope) {
$scope.Message = "Hello World";
} ]);
});

I get the following error Error: ng:areq Bad Argument Argument 'ProductController' is not a function, got undefined

Html is like this

 <body ng-app="myApp">
<div ng-controller="ProductController">
  {{Message}}
</div>
</body>

your iife is not correct, you are missing invoking part of iife(Immediately-invoked function expression), you are not invoking it

(function () { 
var myApp = angular.module('myApp', []);
myApp.controller('ProductController', ['$scope', function ($scope) {
$scope.Message = "Hello World";
} ]);
})();

Working Demo:

(function () { 
var myApp = angular.module('myApp', []);
myApp.controller('ProductController', ['$scope', function ($scope) {
$scope.Message = "Hello World";
} ]);
})();

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="myApp">
<div ng-controller="ProductController">
  {{Message}}
</div>
</body>
