Strategy Pattern vs State 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 meets developers should use the state pattern when an object's behavior depends on its state and it must change its behavior at runtime based on that state, such as in ui components, game characters, or workflow systems. Here's our take.
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
Strategy Pattern
Nice PickDevelopers 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
State Pattern
Developers should use the State Pattern when an object's behavior depends on its state and it must change its behavior at runtime based on that state, such as in UI components, game characters, or workflow systems
Pros
- +It is particularly useful for avoiding large conditional statements (like switch or if-else blocks) that become hard to maintain as states increase, and it adheres to the Open/Closed Principle by making it easy to add new states without modifying existing code
- +Related to: design-patterns, behavioral-patterns
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Strategy Pattern if: You want 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 and can live with specific tradeoffs depend on your use case.
Use State Pattern if: You prioritize it is particularly useful for avoiding large conditional statements (like switch or if-else blocks) that become hard to maintain as states increase, and it adheres to the open/closed principle by making it easy to add new states without modifying existing code over what Strategy Pattern offers.
