Description: Interfaces in Golang are a way to define the behavior of a type by specifying the methods it must implement. This allows different types to be treated uniformly if they fulfill the same interface, thus promoting flexibility and code reuse. In Go, interfaces are implicit, meaning a type does not need to explicitly declare that it implements an interface; it simply needs to have the required methods. This feature encourages cleaner and decoupled design, making it easier to integrate new functionalities without altering existing code. Interfaces also enable more effective testing, as mock types that implement the same interface can be used to verify the behavior of functions that depend on it. In summary, interfaces in Golang are fundamental to programming in this language, providing an efficient way to define and work with common behaviors across different data types.
