TypeScript Types Deep Dive 2

This is the second part of the talk I did in DevSum 2020. It includes:

* enums
* null, undefined and the abscence of value. Why null is evil and what to do about it
* how to DRY your types with advanced types: index access, keyof, typeof, mapped types, utility types, conditional types and infer

Hugs!!!
