Cljs setup for this case probably would require a bit of scaffolding. While using https://github.com/squint-cljs/squint perhaps would be pretty straightforward. Albeit you're gonna lose the type-safety guarantees - Clojure is strongly typed, and Clojurescript sometimes emits safer code than Typescript does (TS removes all the type-related data from the compiled .js code, while Cljs keeps the runtime checks in place). Squint afaik is much closer to Javascript in that respect.

That's cool, I hadn't heard of Squint, thanks! Looks lightweight. Another compile-to-js option that seems good is Gleam.
