In a privately-scoped application, which methods are used for logging messages in server-side scripts?

In ServiceNow, when developing within a privately-scoped application, certain logging methods are recommended for use in server-side scripts to ensure proper logging and debugging. The GlideSystem (gs) object provides several methods for this purpose:

gs.debug():

Description: Logs messages at the "Debug" level.

Usage: gs.debug('Debug message here');

Purpose: Useful for logging detailed information during development and troubleshooting. These messages are typically only visible when the system's logging level is set to "Debug."

gs.error():

Description: Logs messages at the "Error" level.

Usage: gs.error('Error message here');

Purpose: Used to log error messages that indicate a problem that might still allow the application to continue running.

gs.warn():

Description: Logs messages at the "Warning" level.

Usage: gs.warn('Warning message here');

Purpose: Used to log potentially harmful situations that are not necessarily errors but may require attention.

gs.info():

Description: Logs messages at the "Information" level.

Usage: gs.info('Information message here');

Purpose: Used to log informational messages that highlight the progress of the application at a coarse-grained level.

Deprecated or Unsupported Methods in Scoped Applications:

gs.log():

Description: This method is not supported in scoped applications. It is restricted to the global scope and is not accessible from a private scope. Therefore, it should be avoided in privately-scoped applications.
