This document provides an overview of types in Go compared to Ruby. Some key points: - Go uses static, struct-based types while Ruby uses dynamic, class-based types. - In Go, types are defined with the type keyword and methods are defined on specific types. In Ruby, classes define types and inheritance. - Go types are static and checked at compile-time. Ruby types are dynamic and can change at runtime. - Go uses interfaces to define common method sets. Ruby uses mixins and inheritance for polymorphism. The document provides examples of defining types and methods in Go, and uses classes and inheritance in Ruby. It discusses how Go prioritizes static types while Ruby
