1 <p>nothing here {' yet ' + '! '} </p>

Angularjs function: The JSON returned in the background as the model of the front-end. Use HTML for rendering in Angularjs.
Or a background view as a front-end model, and the entire front end is a view of the background.

The NG-APP directive marks the scope of the Angularjs script, and adding the Ng-app attribute in Anuglarjs script tags.
<script src= "Lib/angular/angular.js" ></script>

This line of code loads into the Angular.js script, which executes the Angular.js script when the browser loads the entire HTML page. The Angular.js script will look for an HTML tag that contains the NG-APP directive after it is run. The label defines the scope of the Angularjs app.

The expression of the double brace binding, the binding expression that tells Angularlarjs that the expression needs to be operated on, and inserts the result into the DOM. The DOM can be updated in real time as the result of the expression operation changes.
Angularjs expressions run only in scopes in Angularjs, not throughout the DOM.

<ul><li ng-repeat= ' phone in phones ' >{{phone.name}}<p>{{phone.snippet}}</p></li>< /ul>

Inside the <li> tag, the ng-repeat= ' phpne in phones ' statement is a angularjs iterator. This iterator tells Angularjs to use the first <li> tag as a template to create an LI element for each phone in the list.
