RubyConf 2022: Static typing with RBS in Ruby by Gaurav Kumar Singh

In this talk, we'll generally explore the static type eco system in Ruby. Ruby has two main type checkers Sorbet and RBS. Sorbet was created by the Stripe and RBS is supported by ruby. Sorbet is an annotation base type checking system while RBS is a definition file-based type system. We'll add type annotation for a popular gem using sorbet and RBS and then compare the differences between the two systems. There is lot of interoperability announced between Sorbet and RBS and we'll explore if it's practically possible to convert a sorbet annotated project to RBS.
