stringify/parse edn in clojure/ClojureScript

In JavaScript one can turn a js data structure into a JSON string via

JSON.stringify({somedata: { somesubdata: {}}})

And somewhere else, one can parse it again into a JS data structure via

var my_obj = JSON.parse("{"somedata":{"some_subdata":{}}}");

What would be the equivalent in Clojure/ClojureScript for the edn format?

I want to stringify some data on a ClojureScript front-end and parse it on a Clojure back-end. (and vice versa)
