Except that JVM and CLR are specifications, V8 is an implementation of no specification. There are multiple Java byte code interpreters, multiple JVMs. There is just one V8, and a hack build on top of it called NodeJS. NodeJS doesn't run on any other JavaScript runtime except V8.
NodeJS is like JavaScript as Microsoft VisualJ is like Java.

Maybe this was true back in 2017, but now there's a NodeJS build for the ChakraCore runtime as well.
