helper command to insert session header argument

I write an helper command to insert session header argument easily:

(defun ob-js-insert-session-header-arg (session)
  "Insert ob-js `SESSION' header argument.
- `js-comint'
- `skewer-mode'
- `Indium'
"
  (interactive (list (completing-read "ob-js session: "
                                      '("js-comint" "skewer-mode" "indium"))))
  (org-babel-insert-header-arg
   "session"
   (pcase session
     ("js-comint" "\"*Javascript REPL*\"")
     ("skewer-mode" "\"*skewer-repl*\"")
     ("indium" "\"*JS REPL*\""))))
