what is the behavior of boot-cljs with regards to compiler options defined in the build.boot and in the jsfile.edn? Ie. are these merged? in which order? I am trying to differentiate compiler options between dev and prod.

(for several different build)

Also just curious: what does this do? https://github.com/Deraen/saapas/blob/master/src/cljs/js/main.cljs.edn#L5
