Angular quickstar

Angular quickstart (from CodeSchool) Javascript



app.js:

(function() {
var gem = { name = 'Nick P' };

var app = angular.module('Test', []);
app.controller('StoreController', function() {
this.product = gem;
}
})();
app.html:
<html ng-app="app.js">
<body>
<div ng-controller="StoreController as store">
Product Name: {{store.product.name}}
(Should display "Nick")
</div>
</body>
</html>

"store" is just a locally scoped alias to the StoreController object. It is not available (neither is StoreController) outside the "scope" of the html block in which it is assigned by ng-controller (In this case a div).

My guess is that we want tight scoping on these blocks because interpolating the DOM slows down the page during loading, so we want as little interpolation as possible.
