+Library has `(modes :standard)` so it also builds for bytecode / native
+
+  $ dune build lib/.mylib.objs/byte/mylib.cmo
+  $ dune build lib/.mylib.objs/native/mylib.cmx
+
+Targets are promoted to the source tree
+
+  $ ls ./dist
+  hello.js
+  lib
+  $ ls ./dist/lib
+  mylib.js
+
+  $ node ./dist/hello.js
+  hello
+
+(until-clean) causes JS file targets to be deleted after calling dune clean
+
+  $ dune clean
+  $ ls ./dist
+  lib
+  $ ls ./dist/lib
