A developer is writing code that handles payment processing. The developer wants to log the transaction ID and the status of each step, but must not log credit card numbers or other sensitive data. The developer also wants to ensure that only errors are logged in production to reduce noise. What should the developer do?

Log the transaction ID, status, and the credit card number to a custom log file for complete traceability.

Use `log.info` for transaction status and `log.error` for failures, ensuring no sensitive data is included.

Use `System.out.println` to print the transaction status to the console.

Use `log.debug` for all messages and enable debug logging in production.

A developer is troubleshooting a script that runs on a B2C Commerce instance. The developer wants to set a breakpoint in the script and step through the code to inspect variable values. The developer is using the B2C Commerce development environment. What should the developer do first?

Add a `debugger;` statement in the script and deploy it to the sandbox.

Use the `log` object to print variable values at each step of the script.

Restart the server in debug mode and then open the script in a browser.

Open the script in the debugger and click 'Attach to Server' to connect to the running instance.
