Memento Pattern vs State Pattern
Developers should learn the Memento Pattern when building applications that require state management features like undo operations, version control, or rollback mechanisms, such as in text editors, graphic design software, or game save systems 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.
Memento Pattern

Memento Pattern
Nice PickDevelopers should learn the Memento Pattern when building applications that require state management features like undo operations, version control, or rollback mechanisms, such as in text editors, graphic design software, or game save systems
Pros
- +It helps maintain encapsulation by keeping state details private while enabling external control over state restoration, making code more maintainable and flexible for complex state-handling scenarios
- +Related to: design-patterns, behavioral-patterns
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 Memento Pattern if: You want it helps maintain encapsulation by keeping state details private while enabling external control over state restoration, making code more maintainable and flexible for complex state-handling scenarios 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 Memento Pattern offers.
