Questions

1. Could you please review my explanation comments in the interpretation tasks? I want to make sure I'm understanding the logic clearly.
2. Is my code formatting and variable naming consistent with good JavaScript practice?
3. I tested everything with node, but I’m not sure if I missed any edge cases — is there anything you'd suggest testing differently?
4. Are there any ways I can improve the readability or clarity of my answers?
