I find ClojureScript to be far preferable. The language is much better designed in my opinion. It&#x27;s simple and consistent, while being very flexible and expressive. from what I can tell it does everything ES6 does and more right now.<p>The biggest problem with ES6 is that JavaScript just keeps growing as a language. It has lots of features and quirks already, and more are getting added. This is what you end up dealing with when using ES6 + React (<a href="https:&#x2F;&#x2F;i.imgur.com&#x2F;AjSTP20.png" rel="nofollow">https:&#x2F;&#x2F;i.imgur.com&#x2F;AjSTP20.png</a>).<p>I think the problem with this is that it adds mental overhead when you&#x27;re reading and writing code. Something that looks like it might be doing one thing does something subtly different. This leads to hard to debug errors and wastes you time. It also distracts you from the actual problem you&#x27;re solving.<p>I also find tooling for ClojureScript is better in many areas. Instead of having to juggle things like npm, gulp, grunt, and so on. You can use a single build tool like Leiningen that handles all those things. You have a live coding environment with Figwheel, and you get an editor integrated REPL where you can inspect things easily at runtime.<p>I&#x27;ve been using ClojureScript in prod for about a year now without any issues. I simply wouldn&#x27;t go back to using Js at this point.
