Immutability is really valuable for most application logic, especially:
- State management
- Concurrency
- Testing
- Reasoning about code flow
Not a panacea, but calling it "overrated" usually means "I haven't felt its benefits yet" or "I'm optimizing for the wrong thing"
Also, experiencing immutability benefits in a mutable-first language can feel like 'meh'. In immutable-first languages - Clojure, Haskell, Elixir immutability feels like a superpower. In Javascript, it feels like a chore.
