I disagree with this. I use Clojure and Clojurescript at my day job and know very little JS and virtually nothing from ES6 and beyond. The only time, that I can think of, that I actually needed to directly reference Javascript was when I was needing to do some downloading of files through an API call. I used some of the Google Closure classes as well as Blob. Other than that everything I need is already in a nice clojurescript wrapper over the javascript libraries.
