Chapter Takeaways
- Generics (Go 1.18+) enable writing code that works with multiple types
- Type parameters use square brackets:
func Name[T Type](...)
- Constraints limit which types can be used with generics
- Use generics when you have repeated code patterns that differ only by type
- Don't overuse generics—interfaces or concrete types are often simpler
- The
comparable constraint allows types that support == and !=
- Generic types enable reusable data structures with type safety
