Adding little notes called comments helps AI understand your goal.
40 min · Reviewed 2026
The big idea
Comments are notes inside code that the computer ignores but humans (and AI) read. Adding them helps AI know what you're trying to do.
Some examples
// I want this to count down from 10 to 1.
# Make this happy when the player wins.
Adding a comment then asking 'finish this' often works great.
AI also writes comments — ask 'explain each line with a comment'.
Try it!
Write one line: '// I want a button that says hi when clicked'. Ask AI to write the code that does that.
Practice this safely
Try this with a low-stakes example and a trusted adult nearby. The goal is to notice how AI talks about comments, not to let it make the decision for you.
Ask AI to explain comments in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "How Comments in Code Help AI Help You" and ask for two possible next steps plus one reason each step might be wrong.
Check code clarity against a trusted source, teacher, adult, expert, or original document before you use it.
