compiling ClojureScript code with Lumo is not good experience

and the last command just hangs. probably it's because it's slow.

I don't know how to use it...

src/app/main.cljs

(println "Hello world!")

(require 'lumo.build.api)

(lumo.build.api/build "src" {:output-to "out/main.js"
                             :optimizations :simple
                             :target :nodejs})

maybe I'm wrong.

I thought I could add an example that beginners can compile ClojureScript code to Node.js and run node out/main.js in a few steps. Turned out not as simple as I thought.

You can compile it using clojure just as easily. That's what I'm doing and it's working well

@jiyinyiyong the GCC compiler for js is not as fast as the Java one for sure and there are lot of things that might go wrong. I am compiling with JVM at the moment as well
