In
recompose, the state updaters returned bywithStateHandlersdo not return the new state to the caller at runtime; they trigger an internalsetStateand returnvoid(orundefined).Typing them as returning
ToggleStatecreates a type mismatch (a "type lie") where the compiler believes a value is returned, but at runtime it will beundefined.To ensure type safety and accurately reflect runtime behavior, these handlers should be typed as returning
void.
