Making Choices 🤔
Hi, decision hero! 🌟 Computers can make choices, just like you!
We use a magic word if to say "IF this is true, do something". 🪄
if (true) {
console.log("Yes! 🎉")
}What is True? ✅
Some things are true and some are false.
"The sky is up" is true ☀️. "Fish can fly" is false 🐟. Computers love true and false!
console.log(true)
console.log(false)The if Statement 🚪
An if is like a door. If the rule inside ( ) is true, the door opens and the code inside { } runs!
If it is false, the door stays shut. 🔒
if (true) {
console.log("The door opened! 🚪")
}Comparing Numbers 🔢
We can check if a number is bigger using >.
5 > 3 is true because 5 IS bigger than 3! 🎈
if (5 > 3) {
console.log("5 is bigger! 🎉")
}A Locked Door 🔒
If the rule is false, the code inside does NOT run.
Watch: nothing happens because 2 > 9 is false. 😴
if (2 > 9) {
console.log("You will NOT see this")
}
console.log("But you see this! 👋")Using a Box 📦
We can check the value inside a box!
Here we check if age is big enough for the big slide. 🛝
let age = 10
if (age > 7) {
console.log("You can ride the big slide! 🛝")
}Are They Equal? 🟰
We use === (three equals) to check if two things are the SAME.
"cat" === "cat" is true! 🐱
if ("cat" === "cat") {
console.log("Same animal! 🐱")
}Magic Password 🗝️
Let us make a secret password check!
If the password matches, the treasure chest opens! 💎
let password = "open"
if (password === "open") {
console.log("Chest unlocked! 💎")
}Checking Your Score 🎮
In games, we check scores with if!
If your score is high enough, you win a star! ⭐
let score = 100
if (score > 50) {
console.log("You win a star! ⭐")
}Two Things at Once 🎯
You can put many lines inside the { }! They ALL run if the rule is true.
Like getting two prizes at once! 🎁🎁
if (true) {
console.log("Prize one! 🎁")
console.log("Prize two! 🎁")
}Your Turn to Decide 🧒
Change the number and see if the door opens!
Try making it bigger or smaller than 5. 🚪
let candy = 8
if (candy > 5) {
console.log("Lots of candy! 🍬")
