Typescript 从泛型函数的返回类型创建泛型类型
我想创建一个基本上是返回类型Typescript 从泛型函数的返回类型创建泛型类型,typescript,types,Typescript,Types,我想创建一个基本上是返回类型useState（函数useState（initialState:S |（（）=>S））：[S，Dispatch]）。问题是typeof不能接受泛型参数，这会导致generic参数os useState被推断为unknown type UseStateReturn = ReturnType<typeof useState>; // results in [unknown, Dispatch<unknown>] type UseStateRet
useState函数useState（initialState:S |（（）=>S））：[S，Dispatch]typeofunknowntype UseStateReturn = ReturnType<typeof useState>; // results in [unknown, Dispatch<unknown>]
type UseStateReturn=ReturnType；//结果[未知，调度]
type UseStateReturn<T> = ReturnType<typeof useState<T>>;
type UseStateReturn=ReturnType；
