>> “High-performance polyglot VM. GraalVM is a universal virtual machine for running applications written in JavaScript, Python 3, Ruby, R, JVM-based languages like Java, Scala, Kotlin, and LLVM-based languages such as C and C++.
"Support for Ruby, R, or Python 3 is still experimental in GraalVM. We are actively working on stability and support for all modules for those languages. At this point in time, we can run simpler applications of Ruby and R, but we do not have the same full compatibility we provide for Java and Node.js applications. Our Python implementation was just recently started and can only run small examples."[1]
