Variables are Magic Boxes! 📦✨
Imagine you have special boxes that can hold ANYTHING - numbers, words, even your name!
🤔 What is a Variable?
A variable is like a special box with a name written on it. You can put things inside the box and take them out whenever you need them!
This box holds the number 10!
This box holds the name Sam!

🪄 How to Create a Magic Box
In coding, we create a variable like this:
let favoriteColor = "blue" Says "I'm making a box!"
The name of the box
What's inside the box
🔄 You Can Change What's Inside!
The cool thing about variables is you can change them! Just like emptying a toy box and putting new toys in.
score = 0 Game starts
score = 10 You scored!
score = 25 Even more points!
🎨 What Can You Store in a Variable?
Variables can hold different types of information!
Numbers
age = 10 Words (Text)
name = "Emma" Yes or No
isHappy = true Lists
pets = ["dog", "cat"] 🎮 Think About It!
