Tell us what’s happening:

My code does not even pass task 1. It asks for a function called sortByYear.

Your code so far

const books = [
  {
    title: title1,
    authorName: author1,
    releaseYear: 2001
  },
  {
    title: title2,
    authorName: author2,
    releaseYear: 2002
  },
  {
    title: title3,
    authorName: author3,
    releaseYear: 2003
  }
];

function sortByYear (book1, book2) {
  if (book1.releaseYear > book2.releaseYear) {
    return 1;
  } else if (book1.releaseYear < book2.releaseYear) {
    return -1;
  }
  return 0;
};
