What are Conditionals?
Conditionals help computers make choices. They ask questions and do different things based on the answers - just like you do every day!
🚦 Making Decisions Every Day
You already use conditionals in real life:
🌤️ Real Life Example: Getting Dressed
IF it's raining, THEN take an umbrella.
IF it's cold, THEN wear a jacket.
ELSE (if it's not cold), wear a t-shirt!
💻 How Computers Write It
if (weather ===
"rainy") {
bringUmbrella();
} else {
enjoyTheSun();
}
bringUmbrella();
} else {
enjoyTheSun();
}
