What is Logging?
Recording events and information as your application runs, creating a trail for debugging and analysis.
Why It Matters
Logs are essential for diagnosing issues, understanding user behaviour, and maintaining audit trails.
Real-World Example
A log entry recording that user 123 placed order 456 at 2:34pm, or that an API call failed with error 500.
“Understanding terms like Logging matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
