At least for Java / Scala etc intellij works as it would normally. You just need to point to the graalvm JDK instead of your usual JDK.
Ah I see
GraalVM is just Java :) you don't need a new IDE.
But isn't it more than Java? You can run other languages like Node.js and Python besides Java. So what I'm asking for would be an IDE where I can easily program calls from Java to Node.js or vice versa, for example. Or some other poly-language IDE if such exists
