What is immutability?

Immutability is when something stays exactly the same no matter what happens around it.

Imagine you have a super strong cookie that never breaks or changes shape, even if you drop it, squish it, or throw it at a wall. That’s like being immutable. Once it's made, it doesn’t change.

Think of your favorite toy, maybe a teddy bear that you always carry with you. No matter how many times you play with it, throw it on the floor, or even take it to school, it still looks just like it did when you first got it. That's immutability in action!

Now imagine if your teddy bear changed colors every time you dropped it, that would be mutable. But since it stays the same, it’s immutable, and that makes it extra special.

When something is immutable, we know exactly what to expect from it. That helps us feel safe and confident, just like knowing your favorite toy will always be there for you, no matter what!
