if / else — code that chooses!
A condition is a yes/no question. If the answer is true, the if block runs; if false, the else block runs instead. Edit the gold number and watch the caravan's decision flip live!
🏜️ Caravan Mission Step 1 of 5

In Lesson 4 (Variable Vault) you stored values in variables — tickets, flips, names. A program that only remembers things can't choose. Today you give your code a brain: the if / else statement. It asks a yes/no question, then picks a path. You're the Caravan Master crossing the 🏜️ Desert Oasis — every decision (cross or rest, day or night, open or locked) is an if statement your code decides!
water > 3 is true when water is more than 3.if block runs. If false, the else block runs instead.You just taught your code to think! With if / else, your programs can now make decisions — check the water, feel the heat, count the camels, and pick the right path. Every game-over screen, every password check, every "is it raining?" app — they all run on the if statement you mastered today.
