Shared

React apps needing shared state without prop drilling, derived/computed state that updates automatically, fine-grained re-render control, per-route or per-feature isolated state.
Use TypeScript for any JavaScript project that will grow beyond a few hundred lines or be worked on by more than one person. The upfront cost of adding types pays back quickly in editor autocomplete, safe refactoring, and catching bugs before runtime.
Non-React environments (Jotai is React-only). Complex state machines (use XState). Apps already committed to Redux with large middleware ecosystems.
TypeScript adds a compilation step and a learning curve. For tiny scripts, config files, or throwaway code, plain JavaScript is faster to write. TypeScript's type system also has limits — it can't track runtime behaviour, only the shape of values at compile time.
