🔁 Today's Concept: Loops

A loop tells the computer: "do this step, then do it AGAIN, until you've done it a set number of times." Instead of writing "beep" five separate times, you write it once and say repeat 5. The computer counts each round for you — that count is the heartbeat of every loop!

🧱 body — the step that repeats 🔢 count — how many times ⏱️ run — watch it loop!

← Last time you made code CHOOSE with if / else (Desert Decisions). Today you'll make code REPEAT with a loop!

Loop Complete — You're a Vitals Pro!

You taught the computer to REPEAT with loops. One line, many runs — that's the magic of a loop! 🩺

💫 What You Learned

A loop repeats one step many times — write it once, run it N times.
The body is what repeats (beep a heart, give a pill). You can swap it freely.
The count controls how many times it runs. Change the number, change the output.
A loop obeys you exactly — a wrong count means a wrong result (that's how bugs happen!).
The counter i ticks up each round: 1, 2, 3… that's how the loop keeps track.
