Design patterns are everywhere, as they are the key to managing dependencies between software entities.
But despite their fundamental importance, there are some common misconceptions about them, in particular about several of the most often used design patterns:
Factory functions are frequently mistaken for the Factory Method design pattern
The Builder design pattern is often associated with the implementation of constructors
The Bridge and Strategy design patterns are regularly mixed-up
The modern form of the Visitor design pattern, std::variant, is often considered a replacement of virtual functions
(Bonus) The Decorator design pattern is sometimes mistaken as the Chain of Responsibility design pattern
In this talk I'll shed some light on these misconceptions and explain why they obstruct the proper communication about software design and architecture. Additionally, I’ll address the biggest misconception of all: design patterns are a tool for object-oriented programming.
