Some Examples
In each of these example learn to add, edit, delete a single item in the state

// arrays
const [todos, setTodos] = useState (["Learn hooks", "learn contextapi"])

// arrays of object
const [todos, setTodos] = useState ([
  {
    id: 1,
    name: "Learn hooks!",
  },
   {
    id: 2,
    name: "Learn hooks!",
  },
]}

// objects
const [formData, setFormData] = useState({
  username: "",
  password: ""
})

// objects that contains array
const [person, setPerson] = useState({
  id: 2,
  name: "Baraka",
  age: 28,
  followers: [
     {
        id: 3,
        name: "Winston",
        age: 43
      },
     {
        id: 15,
        name: "Anna",
        age: 22
      },
  ]
})
