Let’s see if we can make the AngularJS application to interact with some user generated data. Let’s try something slightly more advanced. You have a basic AngularJS Hello World application. This technique is good to use during the development process but advised against for production code. By pulling AngularJS from a remote server we avoid having to store it loacally on our computers. Ī CDN (Content Delivery Network) is a collection of global servers that caches and delivers content such as images, videos and Javascript files. AngularJS outputs data stored in the variable message where the expression is written.The ng-init directive initializes AngularJS application variable message.The ng-app directive tells AngularJS that the element is the owner of the application.AngularJS starts automatically when the web page has loaded.
