It is not easy, or,perhaps even possible, to take reactive programming model A and combine it with reactive programming model B. E.g., the editor in this demo is written in C#/WPF via Glitch, WPF supports data binding to recompile expressions, but since this is what glitch is doing also (at a much more general level), we can't use it with data binding.

You could have glitch for an existing language, but it would look more like ReactJS for JavaScript.
