"Explain this code"

Using AI as an infinitely patient tutor.

Sam has variables, logic, loops, functions and data under her belt (Module 2, nearly done). Late last night, her AI wrote one more line for the reading list. She nodded at it, saved, slept.

This morning: const unread = books.filter(b => !b.finished).map(b => b.title);. Hieroglyphics. Arrows? A b with no introduction? Old Sam would have pretended to understand. New Sam does something better: she pastes it straight back to the AI. Predict what comes back.

Predict the response

Sam pastes the gnarly one-liner back to its own author. Note the last five words of her message: they matter more than everything else in it.

You wrote this for me yesterday: const unread = books.filter(b => !b.finished).map(b => b.title); I don't really understand it. Explain it like I'm brand new to coding.

What do you think the AI will do?

Because here's the thing: using AI as a tutor is a skill, not a habit. Anyone can paste code and read a summary. The learning lives in the follow-ups.

Four questions do most of the work. Explain it like I'm new sets the level. Take it line by line zooms in on the exact squiggle you don't own yet. Why this and not X? surfaces the reasoning behind a choice. What breaks if I remove it? reveals what a piece is actually for. Time to run them on the real thing. You're asking.
