The Command Pattern is one of the twenty-three well-known design patterns described by the Gang of Four (GoF) in their influential book, Design Patterns: Elements of Reusable Object-Oriented Software. It falls under the category of behavioral patterns as it deals with the communication between objects and the patterns of communication. The main idea behind the Command Pattern is to provide a means to decouple the requester of a particular action from the object that performs the action. The pattern encapsulates a request as an object, which allows you to parameterize clients with different requests, queue or log requests for later execution, and support undoable operations. The Command Pattern involves the following key components: the Command, which declares an interface for executing operations, the ConcreteCommand, which defines the binding between the action and the receiver, the Receiver, which knows how to perform the operations, and the Invoker, which holds the commands and decides when to execute them. By employing the Command Pattern, you can achieve loose coupling between objects, simplify the design and maintenance of code, enhance flexibility by choosing and adding new commands without modifying existing code, and support undo and redo functionality easily.
