Why? TypeScript, for example, is used pretty much everywhere these days; all the other languages are completely niche. I dislike the language (mutability everywhere, no standard lib), but it's dominating the frontend world ATM.
I've been using Scala.js in production apps for around 3 years now. Curious in your experience what advantages Clojurescript has over Scala.js. I ask because you often hear things like "best in class" when Clojure devs talk about the frontend development experience.
