allOrNothing interpolation is now used for ng-attr-*, under all circumstances. This prevents
uninitialized attributes from being added to the DOM with invalid values which cause errors
to be shown.
BREAKING CHANGE:
Now, ng-attr-* will never add the attribute to the DOM if any of the interpolated expressions
evaluate to `undefined`.
To work around this, initialize values which are intended to be the empty string with the
empty string:
For example, given the following markup:
<div ng-attr-style="border-radius: {{value}}{{units}}"></div>
If $scope.value is `4`, and $scope.units is undefined, the resulting markup is unchanged:
<div ng-attr-style="border-radius: {{value}}{{units}}"></div>
However, if $scope.units is `""`, then the resulting markup is updated:
<div ng-attr-style="border-radius: {{value}}{{units}}" style="border-radius: 4"></div>

AngularJS 
AngularJS lets you write client-side web applications as if you had a smarter browser. It lets you use good old HTML (or HAML, Jade and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. It automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding. To help you structure your application better and make it easy to test, AngularJS teaches the browser how to do dependency injection and inversion of control. Oh yeah and it also helps with server-side communication, taming async callbacks with promises and deferreds; and makes client-side navigation and deeplinking with hashbang urls or HTML5 pushState a piece of cake. The best of all: it makes development fun!
