To who exactly the references made in clojure.org is written for?

It probably would be also helpful to add links to documentation/guides about differences between Clojure and Clojurescript in regards to namespaces, for example: namespaces are not first class citizens in Clojurescript, i.e.: there’s no *ns* and you can’t do (ns-name *ns*).

Upd: I just have discovered a little hack. In Clojurescript you can do: (symbol (namespace ::_)) for the same effect as (ns-name *ns*) in Clojure.
Furthermore:
in Clojure: (ns-interns *ns*),
in Clojurescript: (ns-interns* (symbol (namespace ::_))) ; note the asterisk
