I had a look too, and it seems it&#x27;s an editor for XML + css-like + javascript... XML is used to describe the interface (there&#x27;s no HTML), CSS is used to style the native components, and Javascript is used to script the whole thing.<p>These are native components. They offer access to some of  the hardware and OS through JS.<p>Looks like &quot;React Native&quot; more than anything, some kind of &quot;jQuery Native&quot;... That&#x27;s pretty interesting.
