For the clojure folks there's https://github.com/fulcrologic/statecharts which a pretty sophisticated implementation that removes the XML requirement (particularly for executable content), yet remaining close to SCXML. XState even gets a reference in the prior art section.

I had used (and would gladly still use) XState, without even knowing about what "statecharts" even means.

I used it with lit.js to help with a drawer-like navigation component that reacts to page width and has many props and internal states. I can't even think how horrible it'd have been without XState. Thank you very much!
