Factory Pattern vs. Concrete Instantiation?

Answer
Factory abstracts creation logic. Frame the concept in practical terms so you can explain it during interview discussion.
When you instantiate objects directly, your code becomes dependent on specific classes. The Factory Pattern abstracts this, allowing you to change or extend instantiation logic without affecting client code. If you have a PaymentProcessorFactory, you can switch between PayPal and Stripe processors without changing the core logic of the application.
