Object-oriented — Programming

: This is about "bundling" data and the methods that work on that data into a single unit (a class) and hiding the internal details from the outside world. It’s like a black box; you know what it does, but you don't need to see the wires inside to use it.

For instance, a "Draw" command could look different for a "Circle" than it does for a "Square," but you can call draw() on both. Why Use It? Object-Oriented Programming

To truly understand OOP, you need to know its four core principles: : This is about "bundling" data and the

: You can use classes you’ve written before in new projects through inheritance. For instance, a "Draw" command could look different

: Troubleshooting is easier because the code is divided into independent pieces.
