In this 27-minute video, we take a deep dive into TypeScript for React developers, focusing on mastering types and interfaces. You'll learn how to define and use types (including intersection, union, and conditional types), work with primitives, tuples, and leverage TypeScript's powerful type system. We'll also cover interfaces, from basic declarations to extending, merging, and even creating generic interface types like APIResponse.

Afterward, we implement TypeScript on an existing Card component, showcasing how using union types and prop interfaces makes development more robust and predictable. We finish by adding a borderStyle prop to the Card component and demonstrate how TypeScript's tooling enhances the overall developer experience. Perfect for React developers ready to level up their TypeScript skills!
