The nicest thing of Elm is how much it feels like Haskell. Have built some fun things with Elm years ago.

The second nicest thing with Elm is the philosophy of if it compiles it works. And to be honest you can get that same feeling with most of Rust as well. Sadly not as much of a haskell feeling but at least it has a warm shadow of some of its functional ancestors.

Elm feels like a simplified Haskell which can handle a single space problem.

These days, though, why not just use Haskell itself? Upstream ghc cancompile to wasm for several major releases now and there are several actively developed web frameworks, some of them very Elm-inspired, e.g. https://haskell-miso.org
