<ul><li ng-repeat="item in items">{{$index}}: {{item.name}}
</li></ul>

ng-show & ng-hide
<html ng-app> <body> <div>
Click me: <input type="checkbox" ng-model="checked"><br/><span ng-show="checked">Yes!</span><span ng-hide="checked">Hidden.</span>

$scope.pop = function() { $scope.names.pop(); }}...<button ng-click=”pop()”>Pop</button>
Scope holds data model per controller. It detects changes so data can be updated in the view.

Filters typically transform the data to a new data type, formatting the data in the process. Filters can also be chained, and can take optional arguments
{{ expression | filter }}
{{ expression | filter1 | filter2 }}
123 | number:2
myArray | orderBy:'timestamp':true
Filters
Friday, June 28, 13
angular.module('MyReverseModule', []). filter('reverse', function() { return function(input, uppercase) { var out = "";
// ...
return out; } });
Reverse: {{greeting|reverse}}<br> Reverse + uppercase: {{greeting|reverse:true}}

when("/databases/add", {controller:AddDatabaseCtrl, templateUrl:"app/add-database.html"}).
otherwise({redirectTo: '/databases'});

Services
Angular services are singletons that carry out specific tasks common to web apps. Angular provides a set of services for common operations.
•$location - parses the URL in the browser address. Changes to $location are reflected into the browser address bar•$http - facilitates communication with the remote HTTP servers via the browser's XMLHttpRequest object or via JSONP•$resource - lets you interact with RESTful server-side data sources
http://docs.angularjs.org/guide/dev_guide.services

<div> {{name}} </div> <!-- rendered by twig -->
{% raw %}<div> {{name}} </div> <!-- rendered by AngularJS -->{% endraw %}
AngularJS + Twig - Avoid conflicts
