Class console

    console

    This class allows the developer to write to the Execution log and to Google Cloud Logging if the script is associated with a standard Cloud Project .

    For full support of Cloud Logging and structured logging, use Logger . The console methods serialize the objects to strings and do not support json Payload as part of the structured logging Log Entry .
