It seems to me that setting up clojurescript project is extremely easy. Basically you need to know only one "build" system(leiningen/boot), as for javascript you would have to know at least few(broccoli/npm/bower/gulp etc). And with leiningen you can do `lein new` as well, although I prefer boot and creating my own files:

  ├── README.md
  ├── build.boot
  ├── resources
  │   ├── index.html
  ├── src
  │   └── cljs
  │       ├── sample
  │       │   ├── core.cljs
  │       └── main.cljs.edn
  └── test
      └── cljs
          └── sample
              └── core_test.cljs
