Wait, why should I implement a logging system?

Implementing a logging system may seem like an additional task in the development process, but its significance cannot be underestimated.

While developers do their best to anticipate every possible issue during development, the reality is that some slip through undetected. This is where logging comes into play, offering a detailed record of events that happened within the application.
