Good article, keep the hard work.

Here's mine:

function findFirstRepeated(gifts) {
  // Code here
  let checkedIds = [];
  let repeated = [];

  gifts.find(item => {
    if (checkedIds.includes(item)) {
      repeated.push(item);
      return item;
    }
    checkedIds.push(item);
  });

  return repeated.length > 0 ? repeated[0] : -1;
}
