    How are JRuby's benefits not the same as IronRuby's?

    by Arne Claassen

    In the description, of IronRuby there is a rather dismissive reference to being able to mix your IronRuby with your IronPython and your C#, followed by "Why would you want to do that, except to torture your developers". This is then almost immediately followed with the glowing review of JRuby which is fantastic "because you can use all your Java code". Hmmm...

    IronRuby and JRuby are in concept identical, i.e. both are implementations on top of VMs that can run other languages, which may or may not be languages that you have legacy code in. So how is this something puzzling on .NET and at the same time the thing that makes JRuby great?

    3 answers:

    - Java language is more involve in lots of cross platform open source project

    - Apparently performance of jruby seems better than ironruby

    - I think that Ruby to run .net programs is cool, but Ruby to run ironPython doesn't seem cool.

    I'm sorry, but none of answers addresses why language interop in the jvm is great, but in the clr it's something you'd to do torture developers. At that point it's just a value judgment of "i like java, but i don't like .net", which may be a valid opinion, but sort of irrelevant in a Ruby VM comparison.
