Object Challenge

Step 1

Create an array of objects called library. Add 3 objects with a property of title, author, status. Title and author should be strings (whatever value you want) and status should be another object with the properties of own, reading and read. Which should all be boolean values. For all status, set own to true and reading and read to false.

Step 2

You finished reading all of the books. Set the read value for all of them to true. Do not edit the initial object. Set the values using dot notation.

Step 3

Destructure the title from the first book and rename the variable to firstBook

Step 4

Turn the library object into a JSON string. There is a specific function that we looked at in the last section that we can use to do this.

Step 1 Solution

const library = [
  {
    title: 'The Road Ahead',
    author: 'Bill Gates',
    status: {
      own: true,
      reading: true,
      read: false,
    },
  },
  {
    title: 'Steve Jobs',
    author: 'Walter Isaacson',
    status: {
      own: true,
      reading: false,
      read: false,
    },
  },
  {
    title: 'Mockingjay: The Final Book of The Hunger Games',
    author: 'Suzanne Collins',
    status: {
      own: true,
      reading: false,
      read: true,
    },
  },
];

Step 2 Solution

library[0].status.read = true;
library[1].status.read = true;
library[3].status.read = true;

Step 4 Solution

const { title: firstBook } = library[0];
console.log(firstBook);

Step 4 Solution

const libraryJSON = JSON.stringify(library);
console.log(libraryJSON);
