The article compares the Optics library with Jotai, focusing on their similarities and differences in state management. Optics is a state management library for TypeScript that uses functional references to compose and decompose application state. It emphasizes ease-of-use and scalability. Both Optics and Jotai allow developers to create independent pieces of state, read and update state, and use it in components. However, Jotai's power lies in its ability to derive new atoms from previous ones, while Optics can also derive optics in a similar fashion. Optics offers methods like findFirst, refine, and max to derive new optics, while Jotai requires developers to implement these behaviors with the low-level atom function. The article highlights the differences in composability and abstraction level of their APIs. Overall, Optics provides a new approach to state management that developers can consider for their projects.
