What are the best practices for overriding methods in Go?

When overriding methods in Go, it's important to follow a few best practices: 1. Use interfaces to define behavior. 2. Keep method signatures consistent. 3. Document your methods clearly. 4. Avoid unnecessary complexity.

Can you explain why using interfaces is important?

Using interfaces allows for more flexible and decoupled code. It enables different types to implement the same methods, promoting polymorphism.

What should I document when overriding a method?

You should document the purpose of the method, any changes in behavior, and how it differs from the original method. This helps maintain clarity.

Are there any common mistakes to avoid?

Yes, common mistakes include not maintaining method signatures, failing to document changes, and creating overly complex overrides that confuse users.

Can you give an example of a good override?

Sure! If you have a base type Shape with a method Area(), a derived type Circle can override Area() to provide its specific implementation using its radius.
