JavaScript JVM Runs Java

Posted by timothy on from the build-a-weirder-mousetrap dept.

mikejuk writes "The world of software is made slightly crazy because of the huge flexibility within any computer language. Once you have absorbed the idea of a compiler written in the language it compiles, what else is there left to gawp at? But... a Java Virtual Machine JVM written in JavaScript seems like another level of insanity. A lone coder, Artur Ventura, has implemented a large part of the standard JVM using JavaScript and you can check the code out on Github. Notice this isn't a Java to JavaScript translator but a real JVM that runs byte code. This means it could run any language that compiles to byte code." Bonus: on Ventura's website is a set of visual notes from a talk he gave titled "My Language Is Better Than Yours."

    So you could write a browser that supports JavaScript in Java, and then run the browser in itself?

    Of course there's a difference. Java is defined as the language that runs on top of javascript. This is simple, it's just a compiled language that runs atop of an . . . interpreted . . . of an interpreted . . . it's a compiled . . . it's a compiled language that runs on an interpreted . . . okay guys, really, what the fuck? I think I just heard the sound of part of the universe and a good chunk of logic spontaneously imploding. I'm going to go cry now, and thanks to these dipshits my tears will probably fall sideways upwards now.

    Fabrice Ballard already wrote an x86 emulator in javascript. Just install the standard x86 JVM inside of that and you're good to go.
