I think maybe they've released this too early, or needed to spend a bit more time on the marketing.<p>How many people thing "A modular Javascript Toolkit!! just what I've been looking for!"<p>Compared to Knockout "Simplify dynamic JavaScript UIs by applying the Model-View-View Model (MVVM)"<p>Backbone "Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface."<p>bootstrap "Sleek, intuitive, and powerful front-end framework for faster and easier web development."<p>I'm not going to dive into your code to find out what you're selling me. You need to tell me what I can do with it, and if I'm interested, then I'll delve deeper.

Check out the templating system:<p><pre><code> &#60;ul c:if="notEmpty(colors)"&#62; &#60;li style="color: $color" c:for="color in colors"&#62; $color &#60;/li&#62; &#60;/ul&#62; &#60;div c:else=""&#62; No colors! &#60;/div&#62; </code></pre> Not sure if that's been done before but I think attaching "display logic" to specific elements in the DOM is interesting.

I didn't spend whole lot of time on checking all the features but I liked the templates and specially try-online tool. Templates are clean, easy to read, and close to final HTML. Compared to other templates it is much better in terms of features and readability. Love the fact that the compiler is already built-in, which is very important for performance.

yfiles for html has a strikingly similar approach to going about doing things.
