There is probably as much value in just disciplining yourself to try and write mostly in pure functions (regardless of language - I'd recommend Javascript or Typescript as it is a joy to use and highly expressive). This has benefits when working in large, long-lived systems where engineers can't keep everything in their head, and people come and go over the years. It is easier to reason about, to refactor, and to test, when you know that the "blast radius" of your function is just the return value.
