Millions of developers love Go for its features, performance, ecosystem, and community. But there’s another, perhaps more compelling reason as well: Go is good for business. In this talk, we’ll review the business of Go, including the value it provides both…

Freedom is nothing without constraints, and Go’s generics gives us a powerful way to build polymorphic types and functions constrained by type sets . Let’s geek out.

[^1]: Go's built-in map type isn't concurrent safe. There's a [`sync.Map`](https://pkg.go.dev/sync#Map) type that can be used as an alternative, but it's generally not recommended unless you have done performance testing to confirm it's faster since it adds…
