Writing Clean & Maintainable Code

What is the benefit of implementing the Factory Pattern in JavaScript?

class UserFactory {
  static createUser(type) {
    switch(type) {
      case 'admin':
        return new AdminUser();
      case 'customer':
        return new CustomerUser();
      default:
        throw new Error('Invalid user type');
    }
  }
}

It makes the code more complex
It improves application performance
It centralizes object creation and enforces consistency
The Factory Pattern centralizes object creation logic and provides a consistent way to create objects. This improves maintainability by: 1) Encapsulating creation logic in one place, 2) Making it easier to modify or extend object creation, 3) Providing a clear interface for object creation, and 4) Allowing for better testing and dependency management.
It reduces memory usage
