Krell looks pretty cool. The article talks about using storybook.js, but I'd love to see it used with clojure.spec. The latter is such a nice way to vet business logic with domain experts.
It is so cool to see how far things have come since ClojureScript first worked with React Native in 2015. Krell is the best REPL for this IMHO, and it does this largely by getting out of your way. :)
