Answer
Different environments use different settings such as DB URLs or logging levels, managed via env variables or configs.
Quick Answer
Environment-specific config means different settings for dev, test, staging, and production — different database URLs, log levels, debug flags, API keys. Use process.env to inject these at runtime. Libraries like config or convict help structure multiple environments. Never commit secrets or production configs — use environment variables and secrets managers.
