Señors @ Scale host Neciu Dan sits down with Daishi Kato, the author and maintainer of Zustand, Jotai, and Valtio — three of the most widely used state management libraries in modern React. Daishi has been building modern open source tools for nearly a decade, balancing simplicity with scalability. We dive deep into the philosophy behind each library, how they differ from Redux and MobX, the evolution of the atom concept, and Daishi's latest project: Waku, a framework built around React Server Components.
