solution with forEach ?

Dears,

I solved this challenge in another way too. If you're interested, let's check it out here ?:

const arr = [];  
const bookTitles = users.forEach( user => {
  user.favoriteBooks.forEach(title=> { 
      arr.push(title.title);
  });
});
console.log(arr);

const favoriteBooks = users.reduce((acc, user) => { user.favoriteBooks.forEach(book => acc.push(book.title)) return acc; }, [])

It's also possible with just forEach in reduce.
