yeah "better programmer overall" seems rather vague. The OP seems to be asking specifically "is it even worth it to stay in JS anymore", not "how do i become a well-rounded individual".
I personally prefer to hedge my bets by doing both backend and frontend work. If you join a smaller place/startup, you may end up having to push both. Saying, "I can build anything and I can help across the entire stack where needed" and showing history to back that up i think is a positive. Yes, a github project in a different stack might come in handy at an interview.
