9.5 Design Patterns

Imagine you're building different houses. You wouldn't design every single door, window, or roof from scratch every time, right? You'd use common, proven designs that you know work well. In software, design patterns are similar. They are like reusable solutions to common problems that software developers face when designing programs. They aren't finished pieces of code you can just plug in, but rather templates or blueprints for how to structure your code to solve specific, recurring challenges. Using design patterns helps developers create programs that are easier to understand, maintain, and change.
