psychology What are they?
Design patterns are not ready-made code that you can copy and paste. They are concepts and templates that describe how to solve a recurring design problem.
Think of them as "best practices" formalized by experienced engineers. They provide a shared vocabulary, allowing developers to say "Let's use a Singleton here" instead of explaining a complex logic flow for 10 minutes.

Maintainability
Patterns promote loose coupling, making your systems easier to update and scale over time.
Pattern Explorer
Explore the three main categories of design patterns.
Observer
Lets you define a subscription mechanism to notify multiple objects about any events that happen to the object they're observing.
Strategy
Lets you define a family of algorithms, put each of them into a separate class, and make their objects interchangeable.
Command
Turns a request into a stand-alone object that contains all information about the request. This transformation lets you parameterize methods with different requests.
