ng-app, ng-init, ng-model, ng-controller, ng-src, ng-repeat
The ng-app directive defines the root element of an AngularJS application & will auto-bootstrap (automatically initialize) the application when a web page is loaded.
The ng-init directive defines initial values for an AngularJS application.
Normally, you will not use ng-init. You will use a controller or module instead.
The ng-model directive binds the value of HTML controls (input, select, textarea) to application data. Can also:
Provide type validation for application data (number, email, required).
Provide status for application data (invalid, dirty, touched, error).
Provide CSS classes for HTML elements.
Bind HTML elements to HTML forms.
