Go Generics: When to Use Them, When to Avoid Them
The article discusses the use of generics in Go programming, highlighting their benefits and potential pitfalls. It emphasizes that generics allow for code reuse and type safety, particularly in utility functions and typed data structures. However, it also warns against overusing generics, which can complicate code unnecessarily.
- ▪Generics enable writing code parameterized by types, reducing code duplication.
- ▪They are particularly useful for utility functions on collections and typed data structures.
- ▪Overusing generics can lead to complex code that is harder to maintain.

UserRepository, ProductRepository, OrderRepository: same structure, same FindByID, same List, same pagination logic. The only difference was the return type. Three copies of the same code. When Go 1.18 shipped with generics, I wanted to merge them all.
