I think they both have their merits. Having a guarantee of zero runtime errors can be a nice thing for certain apps, and I think Elm feels very robust and «safe», if you catch my drift.

I still prefer React, but that might be because I know it better. I do, however, miss the innovations like Suspense.

 

You can get Suspense like behavior with Elm fairly easily. Create a type:

type Request e d = Loading | Completed (Result e d)

And match it up with a simple view function:

suspense : Html msg -> (Result e d -> HTML msg) -> Request e d -> Html msg
suspense loadingHtml childHtml request =
    case request of

        Completed result -> childHtml result

Cool! Yeah that does emulate some of it!
