In the Clojure culture it tends to be seen as virtuous and desiereable when instead of writing out logic that implements rules or state tracking, you work with the rules and state as plain data in nested data structures of maps, vectors, sets, keywords used as symbols, etc.

Things like http routing, schemas of data (malli / spec), having an in-memory "app-db" storing all state for a CloureScript web frontend, etc. You can then employ universal and powerful data traversal/validation/manipulation tools in Clojure to these data structures.
