Clojure Complete Course / State & Concurrency

ref

Learn ref in Clojure with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.

12 min read • Intermediate

ref is an atomic Clojure topic inside State & Concurrency. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what ref changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.

Topic-specific example

clojure-06-07-ref.clj
clojure Try It Live
(def balance (ref 100))
@balance
Edge case / engineering note

Observe when work actually runs, what state crosses the asynchronous boundary, and how completion or failure is surfaced.
