Logging in Node.js

Logging is the process of recording and storing system messages or events in a designated file or console. Logs can be used for debugging, auditing, and monitoring purposes.

Structured Logging

Structured logging, on the other hand, is a practice where logs are formatted in a standardized manner, making them easier to parse, search, and analyze. This helps in identifying patterns, troubleshooting issues, and maintaining system performance.
