What do you think about Dart? They pitch it as an elegant language for everything: browser, WASM, servers, plus every native platform with Flutter.

Too java-y for my taste but I guess I get the appeal.

I have a love/hate relationship with dart.

I like some of the language concepts and I don't mind working with it, but I hate all the nesting and reactive stuff when working with flutter

The guy creating it is a hero. The writer of craftinginterpreters.com

I use it exclusively for flutter, but I think it's a great language. If you come from Java & C background, you are going to find it very similar and good to go right away.

BTW, flutter isn't that reactive at all. You have to run SetState() for the UI to rebuild. Unless you use some third party state management tools.
