Console.loggers Anonymous: A Debugging Roadmap from Local to Production
summary
Live demos show concrete wins: run Node with node --inspect on 9229, attach with VS Code F5 attach and set breakpoints to inspect variables without restarting; add a request-id via crypto to correlate logs; instrument server code with OpenTelemetry spans and view a waterfall in a Jaeger-like UI, where a complex request surfaces 52 nested spans so the slow call and exact failing step are obvious. Console.log yields far less actionable context.
