| Java bytecode was originally never intended to be used with anything other than Java - unlike WASM it's very much designed to describe programs using virtual dispatch and automatic memory management. Sun eventually added stuff like invokedynamic to make it easier to implement dynamic languages (at the time, stuff like Ruby and Python), but it was always a bit of round peg in square hole. By comparison, WASM is really more like traditional assembly, only running inside a sandbox. |

| I think so, but that was the 90s where we needed a lot more hindsight to get it right. Plus that was mostly just Sun, right? WASM is backed by all browsers and it looks like MS might be looking at bridging it with its own kernel or something? |

| ▲ | bgwalter a day ago | parent | prev [-] | | I don't know. The integration of Java applets was way smoother than WASM. Security wise, perhaps a different story, though let's wait until WASM is in wide use with filesystem access and bugs start to appear. |

| And of course the ill-fated Parrot VM associated with the Perl 6 project. |

| ▲ | rhdjsjebshjffn a day ago | parent [-] | | I think that was more of a language-oriented effort rather than runtime/abi oriented effort. | | |
| ▲ | foldr a day ago | parent [-] | | Parrot was intended to be a universal VM. It wasn’t just for Perl. https://www.slideshare.net/slideshow/the-parrot-vm/2126925 | | |
| ▲ | rhdjsjebshjffn a day ago | parent [-] | | Sure, I just think that's a very odd way to characterize the project. Basically anything can be universal vm if you put enough effort to reimplementing the languages. Much of what sets Parrot aside is its support for frontend tooling. | | |
| ▲ | foldr a day ago | parent [-] | | “The Parrot VM aims to be a universal virtual machine for dynamic languages…” That’s how the people working on the project characterized it. | | |
| ▲ | rhdjsjebshjffn a day ago | parent [-] | | I certainly think the humor in parrot/rakudo (and why they come up today still) is how little of their own self image the proponents could perceive. The absolute irony of thinking that perl's strength was due to familiarity with text-manipulation rather than the cultural mass.... |

| It’s not a bad idea. Lot of the same people who worked on JVM were around while the asm - wasm ideas emerged |
