Object-oriented programming

Object-oriented programming (OOP) is a way of writing programs that makes it easier to create and maintain complex systems. OOP is like having a bunch of building blocks that you put together to make something bigger and better. Each of the building blocks is a little like a toy figure and it has specific tasks that it's designed to do. You can take those toy figures and put them together in different ways to make complex structures.

In programming, those building blocks are called "objects" and the tasks that each of those objects is designed to do are called "methods". OOP is a way of telling the computer what objects to use and how to use them together. It also makes it easier to switch out pieces of the program if we want something to work differently.

Objects can also "talk" to each other, meaning they can give or take data from each other. This makes it super easy to create complex programs that can do a lot of different things.
