At the start (early 2018) we had a lot of state managers, who solve actual problems, but not elegant and with some limitations.
Effector tries to solve state-managers users' problems and most parts of limitations.
- Developer-friendly, static type-safe and inference, boilerplate free, insinuating API.
- Maximum update (state and subscribers) performance or minimum library performance cost by compile-time and initial runtime computation.
- Modular, isomorphic, flexible.
- Tiny bundle size.
