Here I am setting the empty object with key (publisher) and value author;

Also I tried and I push them in the empty array

let publisherAutors = {};
let pushedAutorsPerPublisher = [];

With this for loop i`m taking the elements from my library , which are books(objects), and i take out the publishers and the autors

for (let i = 0; i < library.length; i++) {
  const element = library[i];
  autorCount = 0;

I think my problem is here , with the if statements, i wanna compare but something is going wrong

  if (
    element.publisher === element.publisher &&
    element.autor === element.autor
  ) {
    console.log(`Yes`);

Here i push to the empty array

    pushedAutorsPerPublisher.push(element.publisher, element.autor);
    console.log(element.publisher, element.autor);
  }

Here I`m adding key/ value to the empty object, but Its not helping me , because they goes only once in the empty object

  publisherAutors[element.publisher] = element.autor;
}

console.log(publisherAutors);
console.log(pushedAutorsPerPublisher);

My main problem is to make object , or array that holds them and count how many different authors have each publisher .
