Updating context values

📋 Description of content that is out-of-date or incorrect

I am trying to create context and sending a signal as value. Using the example from "Updating context values"
In the example, what should be the type used to create the context?
It can't be number as it is retunring an array with the value and functions.

I found a way of sending the signal as a value of the context, and keeping the right types.

The key is to use "function that returns the type of my value": () => LoggedUser as type.

export interface LoggedUser {
    isLoggedIn: boolean;
    isLoading: boolean;
    user: User | null;
}

const defaultLoggedUser: LoggedUser = {
    isLoggedIn: false,
    isLoading: true,
    user: null,
};

export const LoggedUserContext = createContext<[() => LoggedUser]>([() => defaultLoggedUser]);

Looks like a basic TypeScript type definition to me. I don't see how we can improve our docs to make it more clear for this specific case since we use JS for Solid docs. The TypeScript guide might help though.
