What are the best practices for using methods in Go?

When using methods in Go, it's important to follow a few best practices: 1. Use pointer receivers for large structs to avoid copying. 2. Keep method names descriptive and consistent. 3. Avoid side effects in methods to maintain clarity. 4. Group related methods together for better organization.

Can you explain why pointer receivers are preferred?

Pointer receivers are preferred because they allow you to modify the original struct without making a copy. This is especially beneficial for large structs, as it improves performance and reduces memory usage.

What about method naming conventions?

Method names should be descriptive and follow Go's naming conventions. Use camelCase for method names and ensure they clearly convey the method's purpose. This helps improve code readability and maintainability.

Are there any common mistakes to avoid?

Yes, common mistakes include using value receivers for large structs, not handling errors properly, and creating methods that have side effects. Avoiding these can lead to cleaner and more efficient code.
