Here is your own code. Please go through it and for more just go to plunker

 //JS code
    var app = angular.module('myApp', [])
    .controller('AppController', function($scope) {
        $scope.data = 'Hello';
    });




    //template code
        <div ng-app="myApp">
            <div ng-controller="AppController">
              <h1> {{data}}</h1>
           </div>
         </div>

I think you should keep it separate like this, it'll work

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

OR

var app = angular.module('myApp');

app.controller('AppController', function($scope) {
    $scope.data = 'Hello';
});

Also this syntax is wrong but your error is not because of this

<h1> {{'{{ data }}' }}</h1>

Change

<h1> {{ data }}</h1>

Answer 3

Try to create like this

var jimApp = angular.module("mainApp",  []);

    jimApp.controller('mainCtrl', function($scope){
      $scope.data = 'Hello';
    });


<div ng-app="mainApp" ng-controller="mainCtrl">
    {{ data }}
</div>

Answer 4

var app = angular.module('myApp', [])
app.controller('AppController', function($scope) {
    $scope.data = 'Hello';
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
  <div ng-controller="AppController">
      <h1> {{data}}</h1>
  </div>
</div>

{{'{{ data }}' }} =======> {{data}}

I created a snippet with your provided code and jut this part in html and it's working now. Kindly check this answer.

Thank you.
