Writing Clean & Maintainable Code

What's the benefit of implementing the Command Pattern in JavaScript applications?

class Command {
  execute() {}
  undo() {}
}

class AddUserCommand extends Command {
  constructor(receiver, userData) {
    super();
    this.receiver = receiver;
    this.userData = userData;
  }

  execute() {
    this.receiver.addUser(this.userData);
  }

  undo() {
    this.receiver.removeUser(this.userData.id);
  }
}

To improve code execution speed
To reduce memory usage
To encapsulate operations and support undo/redo functionality
The Command Pattern encapsulates operations as objects, providing benefits such as: 1) Support for undo/redo functionality, 2) Queue and schedule operations, 3) Maintain operation history, and 4) Separate the object that invokes the operation from the object that performs it. This improves maintainability and enables more complex operation handling.
