Updated variable names from abbreviations to full names for better code readability in the log and test log files. This modification provides a clearer understanding of variable roles and improves code maintainability in adherence to Go's best practices.
This commit introduces a new type 'JSONlog' that satisfies the Logger interface for structured JSON logging. This includes new methods 'Debugf', 'Infof', 'Warnf' and 'Errorf' to log messages at different levels and an associated test 'jsonlog_test.go' to ensure correct functionality. This enhances the logging functionality by providing clarity in logs and eases debugging process.
