Strategy Pattern
The Strategy Pattern is a behavioral design pattern in software engineering that defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows the algorithm to vary independently from clients that use it, promoting flexibility and separation of concerns. This pattern is commonly used to select an algorithm at runtime based on context or configuration.
Developers should learn the Strategy Pattern when they need to manage multiple algorithms or behaviors that can be swapped dynamically, such as in payment processing systems with different payment methods, sorting algorithms, or compression techniques. It reduces code duplication, enhances testability by isolating algorithms, and adheres to the Open/Closed Principle, making systems easier to extend without modifying existing code.
