Used dart2js with the option minify:true and the command line flags --trust-type-anotations and -trust-primitives.
UglifyJS2 used with flags --compress and --mangle, since I couldn't find a minified/optimizied build in elm-make.
Advanced optimizations build using lein
Built with fullOptJS sbt command.
Build using gradle with kotlin2js and kotlin-dce-js plugins, then passed to UglifyJS2.
