Tips for categorizing the properties of an object based on their types

interface initialStateInterface {
  user: object;
  age: number;
}

const initialState = {
  user: { username: "", email: "" },
  age: 0,
};

In this code snippet, I have defined an interface type for the initial state containing a user object and an age number. Is there a way to assign specific types to the elements of the user object?

What I'm attempting to achieve is,

user: (username: string,email: string).

Answer №1

define UserType {
    name: string,
    emailAddress: string
}

interface UserState {
  userInfo: UserType;
  yearsOld: number;
}
