Command Pattern
The Command Pattern is a behavioral design pattern that encapsulates a request as an object, thereby allowing for parameterization of clients with queues, requests, and operations. It decouples the sender of a request from its receiver, enabling features like undo/redo functionality, logging, and transaction management. This pattern is widely used in software development to create flexible and extensible command structures.
Developers should learn the Command Pattern when building systems that require operations to be queued, logged, or undone, such as in text editors, GUI applications, or transaction-based systems. It is particularly useful in scenarios where you need to decouple the object that invokes an operation from the one that knows how to perform it, enhancing modularity and testability. For example, in game development, it can manage input handling for different actions.
