In css:
As we all know that CSS is static and we can only use it to make up our wedsite,while under the AngularJS,it becomes dynamic so that the function of it increases a lot. For example,helping users to notice the input Box and reminding which stage they are can be achieved by static CSS.
In ng-model:
It likes an index of the input content,which we can refer to in other places.
Confirmation mechanism:
The main idea of our website,I think,is to communicate with users. Therefore,making sure that all the information we got is valid and safe( to avoid the sql injection) is a critical design,while,the AngularJS should a good choice. The built-in functions in AngularJS are quite useful. Like $error.email,$valid, $dirty ...
Overall,the AngularJS is a perfect framework of javascript. What it has done comes from javascript,thus,to make js much easier,I deserve AngularJS.
