The GraalVM team at Oracle Labs has announced new support in the polyglot virtual machine for users of the Nashorn JavaScript engine. Specifically, they're adding a Nashorn compatibility flag to make migration easier.

Version 1.0 of the GraalVM was announced in April of this year. Billed as a "universal virtual machine," it's designed to run applications written in a range of languages, including JavaScript, Python, Ruby, and R; JVM-based languages, such as Java, Scala, and Kotlin; and LLVM-based languages such as C and C++.
