Although I'm curious, I wouldn't ask you to explain why. You probably have your reasons. But I want to note that I love Elm. Elm is a fantastic language. For what is it made for - to build single-page web app frontends, it is hard to think of a better choice.

And I'm not going to tell you that Clojurescript is necessarily better. However, if your choice is dictated by academic curiosity, by all means, do try Purescript. But if you're seeking a tool that allows you to move fast but at the same time to be not too sloppy, maybe give Clojure a try. Beware though: you will encounter things you probably won't like:

- You will hate JVM startup times until you figure out that you don't have to restart REPL. I have some REPL sessions running for days and weeks.

- You will hate error messages. To be fair though, after using Elm, you will hate error messages in any language. Spec and libraries like Expound do improve things, but error messages never get to the level of Elm-awesome.

- If you have never used Lisp before, you will struggle with parentheses until you find a structural editing tool/plugin that works best for you. But after that, it is tough to live without them.

- And yes, you will miss the static type checker, even after learning Spec. Spec is fantastic, and you can do some pretty neat tricks with it, where for something equivalent in Haskell, you'd have to go Liquid. I missed type inference and static type checker in pretty much every dynamically typed language I've used. Clojure minimizes that feeling, but unfortunately, it never dissipates completely.

Historically, there are two camps of languages with roots in lambda-calculus: ML/Haskell and Lisp.

Clojure from the Haskellers' point of view is "worse is better" of Haskell. Haskell from Clojurists' perspective is "too ceremonial and bureaucratic."

But the truth is - you try to learn Haskell, maybe use for a bit, but the chance that you ever get to the point where you can comfortably use Haskell in production is not great. Admittedly, not too many of us developers ever get there.

With Clojure, you can get there pretty quickly. It is way more pragmatic. And every time I go back to Haskell/ML - there are things I miss that exist in Clojure, and whenever I write Clojure, there are things I miss from Haskell. My life is never will be the same
