Spec and Malli in Clojure feel like effing magic - so expressive, so simple - "data as code" philosophy means validations schemas are first-class citizens that can be manipulated, stored, transmitted, and reasoned about like any other data and that's just beautiful. For some type checks you can express in them, it is nearly impossible to achieve in TS, Rust or even Haskell. Clojure makes the complex feel simple because the language itself is designed around data transformation.
That power of course does come with a price, there does not exist a static analyzer that automatically checks things, even though you can pretty much generate beautiful tests based on specs. I think e.g. Rust teams can have more junior devs safely contribute due to enablement of less variability in code quality - the compiler enforces discipline. Clojure teams need higher baseline discipline but can move incredibly fast when everyone's aligned.
It's saddening to see when Clojure gets outright dismissed for being "untyped", even though it absolutely can change one's perspective about type systems.
