In addition to this, it allows for the integration of those languages in the same project. It has a few other features as well, among which is one that offers Substrate VM, a framework that allows AOT compilation for applications written in various languages. It also allows us to compile JVM bytecode into a native executable.

GraalVM is similar to any other JDK available from other vendors, except that it has Java-based JVM Compiler Interface (JVMCI) support, and it uses Graal as its default JIT compiler. Therefore, it can't just execute Java code but also languages...
