I doubt JavaScript will ever be fully replaced here. JavaScript is a pretty good language for these use cases, and it has a huge ecosystem. But if you want to use a front end framework that compiles to warm then you can do that today. Rust, Go, C# and more all have libraries (only Rust really makes sense though, as the others involve shipping a huge runtime). Just don’t expect it to be any faster than JS.
