The State of Ruby 3 Typing

Ruby 3 will ship with a new feature for type checking, RBS. It provides a language to describe types of Ruby programs, the type declarations for standard library classes, and a set of features to support using and developing type checkers. In this talk, I will introduce the feature and how the Ruby programming will be with RBS.
