An example of an AI chatbot conversation about best practices for interfaces in Golang.
What are the best practices for using interfaces in Golang?
Some best practices include defining interfaces that are small and focused, using them to achieve loose coupling, and favoring composition over inheritance.
Can you explain why small interfaces are preferred?
Small interfaces are easier to implement and understand, promoting flexibility and allowing for more reusable code.
What is the difference between an interface and a struct in Golang?
An interface defines a contract for behavior, while a struct is a concrete data type that can implement one or more interfaces.
How can I use interfaces to improve testing in my Golang applications?
By using interfaces, you can create mock implementations for testing, allowing you to isolate components and test them independently.
