Doesn’t the Clojure way of thinking/programming help you with writing better JavaScript though? I’m a JS Dev and I’ve been looking into Clojurescript to broaden my horizon but I’m also hoping to learn some FP techniques that I can use in my Node/React projects.

I'm a JavaScript developer, and (much to my delight) my team recently switched to a much more FP-heavy style (for example, switching from Flux to Redux for our React app... we even used PureScript for a bit). The differences were night and day; even just prioritizing immutability has transformed our codebase. The project is about ~100,000 LOC, so the benefits we get in maintainability and readability are huge; also, after we switched to Redux, our application's performance jumped tremendously (for several reasons). So, to answer your question more directly, I can emphatically say: Yes!

Hi, I'm a Redux maintainer. I'd love to see a writeup on how your team has been using Redux, what maintainability benefits you've seen, and how the app's performance has improved. If you do write something, please ping me @acemarke and let me know!

I wonder how many people feel the same out of real life experience.

Imperative and mutable objects are still seen as the only way for serious products .. there needs to be a large body of evidence to at least make people consider other options (and I'm not trying to sell my church here, just avoid blindness)

What do you mean by serious products? There are plenty of massive projects written in purely functional languages (e.g. Facebook's Sigma) and while adoption isn't as fast as it could be, things seem to be shifting towards functional/immutable, which makes sense since reasoning about highly parallel code without RT and immutability is pretty much impossible.

> The project is about ~100,000 LOC

And I'd bet money that if that same project were translated into ClojureScript, it would be less than one-third that size for the same benefits.

I've considered pitching it, I'll be honest... We stumbled upon a pretty nice architecture via trial-and-error, but when I read about re-frame recently, I realized that it was the exact same thing except in a cohesive framework and years older than I'd have imagined (IMHO ahead of its time)!

It helps a lot. My C and Python code have improved significantly since I've started learning Clojure.
