TypeScript: Mapped and Conditional Types @ CopenhagenJS

The talk took place on 21. 11. 2019 at CopenhagenJS. Huge thanks to the organizers for making the event happen!

In the talk I explore how to use TypeScript’s mapped and conditional types to enforce validations. Main aim is to show how to use these features of TypeScript, not necessarily how to define validations in the most convenient way.
