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. 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. Helps with server-side communication, taming async callbacks with promises and deferreds. Makes client-side navigation and deeplinking with hashbang urls or HTML5 pushState a piece of cake. Client-side MVC modular style. Models are simple objects in your JavaScript controller functions which are manipulated on the views using scopes. Two way binding + custom watchers for variable change Extension to HTML, i.e. Directives in the shape of custom HTML tags or attributes. Dependency Injection to order Services etc on the go in your code files Best SPA (Single Page Application) modal with services like $routeProvider and $location. Different built in services like $http, $resource, $view etc
 Filters, built-in e.g. for currency, orderby and user defined.

* CanJS is flexible. Unlike other frameworks, it's designed to work in almost any situation. You can readily use third party plugins, modify the DOM with jQuery directly, and even use alternate DOM libraries like Zepto and Dojo. CanJS supports all browsers, including IE8. * CanJS is powerful. Create custom elements with one and two-way bindings. Easily define the behavior of observable objects and their derived values. Avoid memory leaks with smart model stores and smart event binding. * CanJS is fast. It is only about 20k. Its live-binding updates only what needs to be updated without requiring a "diff". * CanJS is friendly. Our fulltime and core team are extremely active on gitter chat and on the forums and always wanting to help.
