I'm not quite sure of the value of the book.

It asks for the value of the book but I thought the titles were the values.

If you are referring to the question that asks: "What is the value of book.genres[3]?" it's looking for one of the genres, not the title.

Which of the questions in the quiz is throwing you off?

The first question is "What is the value of book.genres[3]?". As you can see the book is an object holding 4 properties: title, author, rating and genres. These properties then holds values. The first question is which value is represented in book.genres[3]. As it is an array and array always starts on 0 it would be like this:

book.genres[0] = Classics book.genres[1] = Plays book.genres[2] = Fiction book.genres[3] = Romance

const book = {
   title: 'Romeo and Juliet',
   author: 'William Shakespeare',
   rating: 3.74,
   genres: ['Classics', 'Plays', 'Fiction', 'Romance']
}

Any clearer? If not, just ask again!

That's the correct answer, perhaps you had a typo?

If you used 'Romance', try just Romance. It worked for me.
