What does `process` expose that matters in production services?
Short Interview Answer
Env, args, PID, signals, memoryUsage, exit codes, and stdio — the process control surface.
Detailed Explanation
Use env for config, handle SIGTERM for graceful shutdown, and avoid sync work in signal handlers. `process.exit` abruptly skips cleanup — prefer orderly shutdown. Interviewers often ask how you drain connections on deploy.
