They allow development teams to communicate complex architectural ideas using single phrases (e.g., "Let's use a Singleton here"). The Three Categories of Design Patterns
Provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created.
Lets you produce families of related objects without specifying their concrete classes.

Finding high-quality software architecture resources can feel overwhelming. Many developers search for terms like to find accessible ways to elevate their coding skills.
Design patterns are not specific pieces of code or libraries that you can plug directly into your program. Instead, they are high-level concepts and templates that show you how to structure your code to solve a specific problem. They act as a common language for development teams, allowing engineers to communicate complex architectural ideas with a single phrase.
These patterns explain how to assemble objects and classes into larger structures while keeping these structures flexible and efficient.

The best guides show a messy, tightly-coupled piece of code first, explain why it is bad, and then show how a design pattern cleans it up. A pop-up screamed that his driver was out of date
Defines an interface for creating an object but lets subclasses alter the type of objects that will be created.
The core content of the book is available for free in a web-friendly format on the author's official site, Refactoring.Guru
High-quality resources don't just tell you how to build a pattern; they explicitly teach you when to use it and, more importantly, when to avoid it to prevent over-engineering. Best Practices for Mastering Design Patterns
Defines a subscription mechanism to notify multiple objects about any events that happen to the object they’re observing.
