The recording of steps is called event sourcing and both vuex and redux implement the pattern, I'm sure elm is great but that benefit is not unique to elm

Elm's creator is a visionary [1]. E.g. Redux took inspiration from his thoughts. Rust's compiler error messages also. It was rather common on elm core newsgroup to see him asking for secrecy on new ideas before releasing a new version of Elm.

The negative part is that Elm's development is rather slow and not pragmatic. This is painful on the short term - specially if you come from JS land..
