Benchmarks
Jython, Lua and Ruby will have a good performance benefit for most tasks.
Plus, their threading scheme for launguage contexts works better, so you can have true async.
JEP/Groovy's good until you try to access a lot of different Java objects.
but jep can be a pain to install, and has threading concerns like js
Kotlin is faster, but is more strongly typed and null-checked, so it may be harder to write valid scripts in.
WASM/WASI is a joke.
have you seen its java interop code.
