In this episode of the Bits of Q SOLID Principles series we are going to talk about the Liskov Substition principle.
This principle is all about implementing interfaces. By making sure your implementations follow the Liskov substitution principle you keep your code generic and reduce maintnance cost. We will talk about the principle at the class level but also show how it applies for system level interfaces.
