  const obj2 = object2[key].toUpperCase()

  if (obj1 &lt; obj2) {
    return -1
  }
  if (obj1 &gt; obj2) {
    return 1
  }
  return 0
}

books.sort((book1, book2) =&gt; {

})

// Result:
// {id: 2, name: 'A Tale of Two Cities'}
// {id: 3, name: 'Don Quixote'}
// {id: 4, name: 'The Hobbit'}
// {id: 1, name: 'The Lord of the Rings'}
