Add clearer instructions for beginners at iteration 3.1

[CaptKay]

Hi team,

Firstly, thank you for creating and maintaining this lab! It has been really helpful in my learning journey.

While working through the lab, I noticed that iteration 3.1 might be a bit confusing for beginners who are still getting comfortable with the setup and structure. It would be really helpful to include a short line of instruction or hint in that section—something to guide users on what is expected or how to approach it.

For example, a line like:
// Hint: You can use console.log to print your answers.

Thanks again for all your great work!

Best regards,
Kingsley
