Lumina is a statically typed, web-native language that compiles to JavaScript and WebAssembly.
It has HM type inference, algebraic types, traits, a reactive UI runtime, a REPL, an LSP, and a browser demo written in Lumina itself. The current demo runs without React and uses a Vite plugin that compiles .lm files directly for the browser.

I’d love feedback on the language design, the web-native direction, and the developer experience.
