What's in an (Alias) Name? 🤓
Generic alias types are set to arrive in Go 1.24 (anticipated in February 2025) as part of this proposal, expanding on both type aliases and generics. One key use case for type aliases is enabling refactoring without breaking compatibility. Robert breaks down the fundamentals of type aliases and explains why integrating them with generics required additional effort.
