What are mappings?

A mapping is like a special kind of instruction that tells you how to move things from one place to another.

Imagine you have a toy box full of different toys, cars, blocks, and balls. Now imagine you have another box, and you want to put each toy in the new box according to its type: all the cars go together, all the blocks go together, and all the balls go together. That's like doing a mapping, you're matching things from one group (the old box) to another group (the new box).

Think of a mapping as a list of instructions: “If I see a car, put it in the red section. If I see a block, put it in the blue section.” This helps you sort things quickly and easily.

You can also think of it like a secret message, each toy has a new home, and the mapping is the clue that tells you where to send it.

We use mappings all the time. For example, when you're playing a game and you match cards or numbers, you’re using a mapping! It helps make things organized and easy to understand, just like sorting your toys.
