1. A type of object would look something like this:

             type UserData = {
  name: string,
  age: number,
  status: boolean
}

2. Using the type object to initialize a new state:

type UserData = {
  name: string,
  age: number,
  status: boolean
}


// New State
const [user, setUser]=useState<UserData>({name: 'Johnn Doe', age: 12, status: true})

Optional fields

type UserData = {
  name?: string,
  age?: number,
  status?: boolean
}
// New State
const [user, setUser]=useState<UserData>({age: 12})
