Tried docs https://clojuredocs.org/clojure.core.async but found nothing like chan?
. How to tell if a value is a channel?
It is a bit ugly at the moment but you can use the core.async protocols and check for those.
(ns foo.util
(:require [cljs.core.async.impl.protocols :as async-prot]))
(defn chan? [x]
(satisfies? async-prot/ReadPort x))

I’ve been using these:
clojure
(defn channel?
[x]
(satisfies? clojure.core.async.impl.protocols/Channel x))
clojurescript
(defn channel?
[x]
(satisfies? cljs.core.async.impl.protocols/Channel x))
