Problem Statement
What are some trade-offs when you apply OOP best practices and how do you decide when to use them or avoid over-engineering?
Explanation
Applying OOP best practices like SOLID, composition, and dependency injection brings numerous benefits—modularity, testability, and maintainability. /n/n However, there are trade-offs: they often require more classes and abstraction layers, which can increase complexity and reduce clarity. Over-engineering might slow down development, complicate debugging or tie up resources. /n/n You decide to apply them when the system is complex, expected to evolve, or needs to be maintained long-term. For simpler, short-lived scripts or prototypes, you may prefer simpler designs. The key is to balance pragmatism and sound design—not every class needs an interface just because best practice suggests it.
