Echo JS 0.11.0

I believe JavaScript is a bad language so I switched to ClojureScript half a year ago.

I doubt that React can do that now. Maybe, but not perfect. Like you said, multiple root components. But if the app is complicated, you may want to route pages with React. Then it's  not enough.

Check this to see how this page was written in CirruScript itself.
