> The ReasonML debugger supports time-travelling as one of its features.

Yes, but the question is: does it guarantee to be working or is it only "sort of" working? Can your view do side-effects? Can it call JS? If yes -- it will break soon.

> The Bucklescript compiler that backs ReasonML provides dead-code elimination.

I didn't say it doesn't. I said it will be way more poor than the one Elm has. I don't have the link, but Todo app in Elm weights less than the one made in React, that's how good it is.




Interesting since OP says time-traveling is not mature in ELM

Tooling isn’t mature. IDE plugins, time travel “debugger” : they cannot compare yet with our usual Dev XP for TS


Well, it's one thing to not be mature yet (UI could definitely be improved, it's very minimalistic currently, but works ok for me), and another to not work in principle :)
