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.
