All: please don't take threads like this on generic tangents, especially not generic flamewar tangents, including programming language/framework flamewar tangents. Those are repetitive and tedious. We want interesting, curious discussion. That usually comes from engaging with the specifics of the article. https://news.ycombinator.com/newsguidelines.html

For the reverse, I wrote a WASM-to-JVM compiler: https://github.com/cretz/asmble. I think WASM has the ability for us to finally cross the language boundaries without marrying ourselves to C/C++ ABI. But at this early stage, there's no common stdlib for all languages to share.

I wish projects like this and RoboVM worked, but in my experience they’re a pain to set up, without much documentation, and they fail on weird Java edge cases.

Recently found out about this project when my friend made a Runescape webclient that works in the browser, reminded me of the low friction gaming back in 2006 ^^
