Obviously you gotta work with what you got and it might be the best business decision to hire some junior devs with no experience outside of JS/TS and build your CLI tool in that.
But that's never going to be the best tool for CLI development, and someone with no experience outside of JS/TS (or any single language) is never going to be the best engineer.
