"AngularJS is a JavaScript framework which simplifies binding JavaScript objects with HTML UI elements."
The javascript class is attached to a HTML parent div tag using ng-controller directive and the properties are binded directly to the text box using ng-model declarative.
So now whatever you type in the textbox updates the Customer object and when the “Customer” object gets updated it also updates the UI.
<div ng-controller="Customer">
<input type=text id="txtCustomerName" ng-model="CustomerName"/>
</div>In short if you now analyze the above code visually you end up with something as shown in the below figure.
