// constructor function

function Book(title, author, pages, read = false) {
  this.title = title;
  this.author = author;
  this.pages = pages;
  this.read = read;
  this.status = function() {
    console.log(this.read);
  }
}

// array to store objects

let mybooks = [];

// instances of the Book object

let book1 = new Book('Hello', 'John', 123, true);
let book2 = new Book('Hey', 'Jane', 13, false);
let book3 = new Book('Hi', 'Mary', 12, true);
let book4 = new Book('Holo', 'Peter', 10, false);
let book5 = new Book('Banda', 'Banda', 03, true);

// push the instances to the mybooks array

mybooks.push(book1);
mybooks.push(book2);
mybooks.push(book3);
mybooks.push(book4);
mybooks.push(book5);

// store mybooks to the localStorage

localStorage.mybooks = JSON.stringify(mybooks);

// retrieve data from the localStorage

let data = JSON.parse(localStorage.getItem('mybooks'));

// call the status() method on each object

data.forEach(book => {
  book.status();
});
