JSON was used in the original article as a placeholder for Clojure forms. You can (optionally) get strong typing using Clojure records[1] (see defrecord) or using core.typed[2]. Datomic also lets you specify types[3]. I'm not "coming back" to you, as I don't appreciate your snarky, know-it-all tone. I'm replying for the benefit of others reading who may not be familiar with Clojure.
