There's been a few flash runtimes in javascript and other languages. Most of them have been long abandoned. https://github.com/tobeytailor/gordon https://github.com/tobeytailor/gordon https://www.gnu.org/software/gnash/ https://www.gnu.org/software/gnash/ In development: https://github.com/lightspark/lightspark https://github.com/lightspark/lightspark https://github.com/ruffle-rs/ruffle https://github.com/ruffle-rs/ruffle And then the most recent one, CheerpX, which as I understand it runs the Adobe flash runtime itself via wasm: https://leaningtech.com/pages/cheerpxflash.html https://leaningtech.com/pages/cheerpxflash.html Which brings me to Java. Java left the browser even before flash did. Not all of these are javascript jvms, but all of them are intended to run Java applications in the browser (some are transpilers, others require code changes): https://leaningtech.com/pages/cheerpj.html https://leaningtech.com/pages/cheerpj.html https://github.com/java2script/java2script https://github.com/java2script/java2script (this links to some less-complete projects) https://github.com/Jivings/jsJVM https://github.com/Jivings/jsJVM https://github.com/nurv/BicaVM https://github.com/nurv/BicaVM https://github.com/st-js/st-js/ https://github.com/st-js/st-js/ https://github.com/plasma-umass/doppio https://github.com/plasma-umass/doppio https://github.com/jtulach/bck2brwsr https://github.com/jtulach/bck2brwsr https://www.keithschwarz.com/+script/ https://www.keithschwarz.com/+script/ https://github.com/robterrell/orto https://github.com/robterrell/orto https://github.com/jdstroy/JavaPoly https://github.com/jdstroy/JavaPoly https://gitlab.com/neoexpert/jvm/-/blob/master/jsjvm/README.md https://gitlab.com/neoexpert/jvm/-/blob/master/jsjvm/README....
