Probably not very useful for much, but here's some basic syntax to update an
atom from javascript just in case anyone is interested/for posterity:
//create the atom in cljs.user> (def (atom {:foo "bar"}))
//then it's possible change the value from javascript like this:
var new_val =
cljs.core.PersistentArrayMap.fromArray([cljs.core.keyword("foo"),"baz"]);
cljs.core.swap_BANG_(cljs.user.app, function (){return new_val});
//cljs.user> @app
// => {:foo "baz"}
