What are the key milestones in the history of software design patterns?

The history of software design patterns began in the 1970s with the emergence of object-oriented programming. One key milestone was the publication of the book 'Design Patterns: Elements of Reusable Object-Oriented Software' by Gamma et al. in 1994, which introduced 23 classic design patterns.

Can you explain some of these classic design patterns?

Sure! Some classic design patterns include the Singleton, which ensures a class has only one instance, and the Observer, which allows a subject to notify observers about changes.

How have design patterns evolved since then?

Design patterns have evolved to address new programming paradigms, such as functional programming and microservices. New patterns have emerged to tackle modern challenges in software architecture.

What are some contemporary design patterns?

Contemporary design patterns include the Repository pattern for data access, the Circuit Breaker pattern for fault tolerance, and the Event Sourcing pattern for state management.
