Design Pattern is a common topic in talks, forums and even in a 15 min break conversation at work. You can find a lot of stuff on books or the internet about it and a lot of examples using rubber ducks 🦆, coffee shop ☕ and pizza stores 🍕.When I started studying I usually understand the pattern but I had a lot of trouble, thinking about how to apply them to my code. I understand that the Factory pattern is used to create objects but why do I need it?
