Mis on peamine probleem rakenduses sisseehitatud logija kasutamisel?

The main problem with the built-in logger in Go (log from the standard library) is its limited functionality:

• Lack of logging levels (e.g., DEBUG, INFO, ERROR), which makes filtering messages difficult.
• No support for structured logging (key-value), which complicates log analysis.
• Limited options for configuring format and output (e.g., it is not easy to redirect output to a file or external system).

Because of this, more complex applications often use third-party logging libraries such as zap, logrus, or zerolog, which provide extended capabilities and flexibility.
