Delegation Pattern vs Strategy Pattern

Developers should learn the Delegation Pattern when they need to avoid tight coupling, enhance modularity, or simulate multiple inheritance in languages that don't support it directly meets 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. Here's our take.

Delegation Pattern

Nice Pick

Developers should learn the Delegation Pattern when they need to avoid tight coupling, enhance modularity, or simulate multiple inheritance in languages that don't support it directly

Pros

• It's particularly useful in scenarios like event handling, where an object delegates event responses to a handler, or in frameworks like iOS development with protocols and delegates
• Related to: design-patterns, object-oriented-programming

Cons

• Specific tradeoffs depend on your use case

Strategy Pattern

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

Pros

• 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
• Related to: design-patterns, object-oriented-programming

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Delegation Pattern if: You want it's particularly useful in scenarios like event handling, where an object delegates event responses to a handler, or in frameworks like ios development with protocols and delegates and can live with specific tradeoffs depend on your use case.

Use Strategy Pattern if: You prioritize 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 over what Delegation Pattern offers.

The Bottom Line

Delegation Pattern wins

Developers should learn the Delegation Pattern when they need to avoid tight coupling, enhance modularity, or simulate multiple inheritance in languages that don't support it directly
