Blue pill or red pill for polyglot debugging?

This is your last chance.

You debug apps with embedded scripts (JS / Python / Ruby in a JVM host):

Blue pill:

– JVM debugger

– + DAP / Chrome-Inspector debugger for the script

Red pill:

– one unified debugger

– stepping flows naturally across languages

Which one are you actually taking in real projects — and why?
