AngularJS: $scope not binding to view when using ng-repeat - angularjs

For some reason when I use ng-repeat the $scope variable does not bind its data to the view. It's been driving me insane because I figure out what i'm doing wrong in this case. In the when I console.log the $scope variable, its there but it just refuses to bind to the view when i'm using ng-repeat. In this case the word "movie" in the paragraph tag is repeated 3x but there's not data to go with it. Here is the code below:
<html ng-app="myApp" ng-controller="IndexCtrl">
<head>
<base href="/">
<title>Page Title</title>
</head>
<body>
<div>Hello World!
<div ng-repeat="movie in movies">
<p>movie: {{movie.moviename}}</p>
</div>
</div>
<script src="bower_components/angular/angular.js"></script>
<script src="bower_components/angular-route/angular-route.js"></script>
<script type="text/javascript">
var myApp = angular.module("myApp", []);
function IndexCtrl($scope) {
$scope.movies = [
{'moviename':'ironman'},
{'moviename':'antman'},
{'moviename':'man'}
];
console.log($scope.movies);
};
</script>
</body>
</html>

After long sleepless nights lol I figured out the answer. Apparently the problem was with my node js express server using mustache as a middleware to template html. It uses the {{ }} symbols as well so angular never got to interpret what was going on. So I used $interpolateProvider to change the angular symbols and now it works beautifully.
var myApp = angular.module('myApp', [], function($interpolateProvider) {
$interpolateProvider.startSymbol('[[');
$interpolateProvider.endSymbol(']]');
});
To anyone else using a node.js backend and not using jade as a template language, I hope this helps!

It would be better to explicitly define the controller inside the module:
var myApp = angular.module("myApp", []);
myApp.controller('IndexCtrl', function($scope) {
$scope.movies = [
{'moviename':'ironman'},
{'moviename':'antman'},
{'moviename':'man'}
];
console.log($scope.movies);
});
But.... I copied the code exactly, replaced angular resource path. And all is working.
<html ng-app="myApp" ng-controller="IndexCtrl">
<head>
<base href="/">
<title>Page Title</title>
</head>
<body>
<div>Hello World!
<div ng-repeat="movie in movies">
<p>movie: {{movie.moviename}}</p>
</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script type="text/javascript">
var myApp = angular.module("myApp", []);
function IndexCtrl($scope) {
$scope.movies = [
{'moviename':'ironman'},
{'moviename':'antman'},
{'moviename':'man'}
];
console.log($scope.movies);
};
</script>
</body>
</html>

Is it possible to use more than one ng-app in angular1?If yes ,In which condition we do it and how to register to angular module

I am trying to add more than one ng-app in a application ,how to register the both ng-app and let me know what is the use of using more than one ng-app?
Only one AngularJS application can be auto-bootstrapped per HTML document. The first ngApp found in the document will be used to define the root element to auto-bootstrap as an application. To run multiple applications in an HTML document you must manually bootstrap them using angular.bootstrap instead. AngularJS applications cannot be nested within each other.
var app1 = angular.module('app1', []);
app1.controller('Ctrl1', function ($scope)
{
$scope.name = "Angular";
});
var app2 = angular.module('app2', []);
app2.controller('Ctrl2', function ($scope)
{
$scope.name = "Developer";
});
angular.element(document).ready(function() {
angular.bootstrap(document.getElementById('app2'), ['app2']);
});

AngularJs not compiling

I created a basic AngularJS app and it's not displaying the values on the live site declared on the controller.
The live site displays the expressions written on the controller file instead.
ie. - It displays:
{{ title }}
{{ paragraph }}
Instead of:
First Angular Title
First Angular Paragraph
index.html:
<!DOCTYPE html>
<html>
<head>
<title>Angular Application</title>
<script src="js/shared/angular.min.js"></script>
</head>
<body ng-app="mainApp">
<div ng-controller="MainController">
<h1> {{ title }} </h1>
<p> {{ paragraph }}<p>
</div>
<!-- Modules -->
<script src="js/app.js"></script>
<!-- Controllers -->
<script src="js/controllers/MainController.js"></script>
</body>
</html>
MainController.js
app.controller("MainController", ['$scope', function($scope) {
$scope.title = "First Angular Title";
$scope.paragraph = "First Angular Paragraph";
}]);
app.js
var app = angular.module("mainApp", []);
I don't know what I'm doing wrong. I'm completely new to this. I appreciate any help. Thanks for your time.
I have included the angular from cdn and updated the inline script the same working. please verify included files are loading properly.

Referencing local angular.js does not work

I'm beginning to work with AngularJS and am having trouble working with a local copy of the angular.js file. Below is the sample I am trying to get to work. When I reference the CDN script, the page correctly displays 'Hello, World'. When I reference the local script, the binding does not occur. The browser is able to locate the local angular.js file, it just doesn't seem to perform the binding.
<html ng-app>
<head>
<title></title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.4/angular.js"></script>
<!--<script src="Scripts/angular.js"></script>-->
<script>
function HelloController($scope) {
$scope.greeting = { text: "Hello" };
}
</script>
</head>
<body>
<div ng-controller="HelloController">
<p>{{greeting.text}}, World</p>
</div>
</body>
</html>
If I was starting out with 1.3.15 would do something like this:
<html ng-app="main.app">
<head>
<script src="https://code.angularjs.org/1.3.15/angular.js"></script>
<script>
angular.module('main.app', [])
.controller('HelloController', function () {
var self = this;
this.greeting = { text: "Hello" };
})
</script>
</head>
<body ng-controller="HelloController as HelloCtrl">
<p>{{HelloCtrl.greeting.text}}, World</p>
</body>
</html>
This follows the latest styles of angular coding

Why is ng-bind-html not displaying anything?

I am displaying a string that has HTML code in it:
<div style="font-size: 14px" ng-bind="currentBook.description"></div>
put it displays the HTML code instead of interpreting the elements:
When I use ng-bind and ng-bind-unsafe, it shows nothing.
How can I get the HTML to be parsed?
Addendum
I added a reference to sanitize but ng-bind and ng-bind-unsafe still show nothing:
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular-route.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.8/angular-sanitize.js"></script>
Ok, I added the ngSanitize var app = angular.module('app', ['ngSanitize']); and now it works.
It looks like you missed ngSanitize please see demo below
You can find more here
https://docs.angularjs.org/api/ngSanitize/service/$sanitize
var app = angular.module('app', ['ngSanitize']);
app.controller('firstCtrl', function($scope, $sce) {
$scope.currentBook = {
description: "<p>some description</p>"
};
});
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.8/angular.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.8/angular-sanitize.js"></script>
<body ng-app="app">
<div ng-controller="firstCtrl">
<div style="font-size: 14px" ng-bind-html="currentBook.description"></div>
</div>
</body>
call apply
$scope.$apply(function () {
$scope.currentBook.description = $sce.trustAsHtml(html);
});

Egghead angular controller not working

I am trying to follow along on the eggheads angularJS tutorials. I have the same code however mine is not working...
Here is the code I am using:
index.html:
<!DOCTYPE html>
<html>
<head>
<title>AngularJS Tutorials</title>
<link rel="stylesheet" href="../foundation/css/foundation.min.css">
<script type="text/javascript" src="main.js"></script>
</head>
<body>
<div ng-app="">
<div ng-controller="FirstCtrl">
<h1>{{data.message + " world"}}</h1>
<div class="{{data.message}}">
Wrap me with a foundation component.
</div>
</div>
</div>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.4/angular.min.js"></script>
</body>
</html>
main.js:
function FirstCtrl($scope) {
$scope.data = {message: "panel"};
}
The problem is angular version.
Your version is 1.3.4 instead of 1.2.3.
App with angular 1.2.3 (egghead) : plunkr
App with angular 1.3.4 :plunker
Hi you've missed couple thing
Declaration of you app :
var app = angular.module('app', []);
Declaration of your controller
app.controller('FirstCtrl', FirstCtrl);
In your html
ng-app="app"
var app = angular.module('app', []);
app.controller('FirstCtrl', FirstCtrl);
function FirstCtrl($scope) {
$scope.data = {
message: "panel"
};
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="app">
<div ng-controller="FirstCtrl">
<h1>{{data.message + " world"}}</h1>
<div class="{{data.message}}">
Wrap me with a foundation component.
</div>
</div>
</body>
