Oh, ok I thought the demo was a picture because nothing happended when you clicked the thing... The JS version has very high latency. How does it work under the hood? Can the same pipeline port Java Applets to WASM/JS?

It literally is the first thing you see. The docs at https://minigdx.github.io/tiny/ https://minigdx.github.io/tiny/ have a demo "BREAKOUT" game embedded in the page under the first paragraph with a link to the source code lol Screenshot for reference: https://i.imgur.com/TVzQwiu.png https://i.imgur.com/TVzQwiu.png

  I think it would be more interesting to expose how the bytecode becomes JS. But I guess I'll dig through at some point... nm, that breakout (that you could run on a 6502) maxxes a 15W modern CPU core. That's 10.000x less efficient.

There's no bytecode emitted -- Kotlin is unique among JVM languages in that it acts more like a frontend, similar to LLVM or GCC. The Kotlin code is translated from an IR/AST into JS directly. The JS is one of many target languages for the Kotlin compiler. Kotlin Source Code | Kotlin Compiler | IR / / \ \ JVM WASM Native JS

        Scala has good parts?

    browser games no have fps limiter and/or vsync? oh i forgot, 2000 fps is good for bragging rights

Not sure about Kotlin, but there is alreadt CheerpJ that can run Java applets unmodified both as normal JS, or as WASM. For non-applets there is even more possibilities: there is google’s closure compiler and teawm, both can produce really great code!
