It depends on what kind of project you are using it for.

Hobbyist/toy project - sure, using shadow-cljs you can do your front end entirely in ClojureScript and make calls out to whatever backend you want

Professional project with ClojureScript backend - sure, you can use shadow-cljs to target both node (using :node target) and the browser which will allow you to utilize ClojureScript for full stack and not have to rely on Clojure

Professional Project with non-clojure(script) backend - no. It would not be worth it to spend resources to learn clojurescript (talent pool of existing clojure devs is small) and not taking advantage of full stack clojure(script) can be detrimental
