Start ClojureScript nREPL
# I'm no longer smart enough to learn DSLs to start my favourite language REPL.

# If anyone from Cognitect is reading this, AFAIC this stuff is the biggest barrier to Clojure adoption.

# Edit your deps.edn file:
#
# {:deps {org.clojure/clojure {:mvn/version "1.9.0"}
# org.clojure/clojurescript {:mvn/version "1.10.339"}

;; now connect to port 7888. there's probably a way to do this in one line.
