Plan B with else 🅱️

Hi, clever coder! 🌟 What if the rule is NOT true? We need a Plan B!

We use the magic word else for "otherwise, do THIS". 🪄

if (false) {
  console.log("Plan A")
} else {
  console.log("Plan B! 🅱️")
}

If This, Else That 🔀

else always comes right after an if.

If the rule is true, do the first part. Otherwise, do the else part! 🚪🚪

if (true) {
  console.log("Door A 🚪")
} else {
  console.log("Door B 🚪")
}

Sunny or Rainy? 🌦️

Let us decide what to wear!

If it is sunny, wear sunglasses. Else, grab an umbrella! ☂️

let sunny = true
if (sunny) {
  console.log("Wear sunglasses! 😎")
} else {
  console.log("Grab an umbrella! ☂️")
}

Try the Other Way 🔄

Now change sunny to false and see Plan B happen!

One of them ALWAYS runs. 🎯

let sunny = false
if (sunny) {
  console.log("Wear sunglasses! 😎")
} else {
  console.log("Grab an umbrella! ☂️")
}

Big or Small? 📏

Let us check a number!

If it is big, cheer. Else, say it is small. 🎈

let number = 3
if (number > 10) {
  console.log("Big number! 🎉")
} else {
  console.log("Small number 🐜")
}

Pass or Try Again 🎯

In a game, you either pass or try again!

If score is high, you pass. Else, try again. 💪

let score = 40
if (score > 50) {
  console.log("You passed! 🌟")
} else {
  console.log("Try again! 💪")
}

Secret Word Check 🗝️

If the secret word is right, open the chest. Else, keep it locked!

Else makes it safe. 🔒

let word = "wrong"
if (word === "open") {
  console.log("Unlocked! 💎")
} else {
  console.log("Still locked! 🔒")
}

Only One Runs 1️⃣

Remember: only ONE part runs. Either the if OR the else, never both!

It is one or the other. 🤝

if (5 > 100) {
  console.log("This is skipped")
} else {
  console.log("This one runs! ✅")
}

Hungry or Full? 🍕

Let us decide about snacks!

If hungry, eat. Else, go play! 🎮

let hungry = true
if (hungry) {
  console.log("Time for a snack! 🍕")
} else {
  console.log("Time to play! 🎮")
}

Day or Night? 🌞🌜

If it is day, play outside. Else, go to sleep!

Change isDay and see what happens. 😴

let isDay = true
if (isDay) {
  console.log("Play outside! 🌞")
} else {
  console.log("Time to sleep! 🌜")
}

Your Turn for Plan B 🧒

Change the number and watch which plan runs!

You are in control. 🎮

let stars = 2
if (stars > 5) {
  console.log("Superstar! 🌟")
} else {
  console.log("Keep collecting! ⭐")
}
