Depends on your requirements. If you want statically compiled (AOT compiled), then I think Nim, Zig, or even Rust are good alternatives.

If you like the high-performance backend, then Java, Kotlin, Scala, or C# are great choices.

Do you mean for production? Zig isn't production-ready. Nim is extremely niche. I'm kind of puzzled why I see these thrown around so much on HN. Sure, they're fine for a side-project, but they're pretty out there for anything mission critical.
