Clj-kondo
A linter for Clojure code that sparks joy
... you run clj-kondo. Before linting inside your editor, it is recommended to lint the entire classpath to teach clj-kondo about all the libraries you are using, including Clojure and/or ClojureScript itself. Since clj-kondo now knows about your version of ClojureScript via the cache, it detects that the number of arguments you passed to select keys is invalid. Each time you edit a file, the cache is incrementally updated, so clj-kondo is informed about new functions you just wrote.
