After reading the article, Clojure would probably be better suited to be mentioned than ClojureScript. The point of it all looked to be speaking to the new paradigm that Phoenix LiveView brings which is server side rendering of subsections of a page. ClojureScript, while being Clojure in a Javascript uniform, doesn't look to be used in that manor.
It's all good. Everything being said, I appreciate efforts like ClojureScript. There is just so much power in being able to use the same language and share the same models on the front and back end, but not all of us want to use JavaScript/Typescript.
