Why Doesn't Go Have Built-in Generics?

Generics in Go: An Ongoing Discussion

Generics have been a topic of discussion among Go developers for quite some time, despite the absence of true support for them in the language. This question explores the reasons behind this lack of support.

According to a response on the Go FAQ page, the developers do not feel an urgent need for generics and believe that the complexity introduced might not be worth the benefits. They acknowledge the convenience of generics, but emphasize the need for a design that provides sufficient value in relation to its complexity.

While generics are not explicitly supported in Go, it is possible to achieve similar functionality through the use of built-in maps and slices. Additionally, the empty interface allows for the construction of containers that can hold any type with explicit unboxing.

The FAQ concludes by stating that the discussion on generics remains open, indicating that the issue is still being considered by the Go team.
