Tell us what’s happening:

this.items.forEach((dessert) => {
totalCountPerProduct[dessert.id] = (totalCountPerProduct[dessert.id] || 0) + 1;
})
What do i even do, this part feels too wrong

Your code so far

<!-- file: index.html -->


/* file: styles.css */


/* file: script.js */
// User Editable Region

  addItem(id, products) {
    const product = products.find((item) => item.id === id);
    const { name, price } = product;
    this.items.push(product);

    const totalCountPerProduct = {};
    this.items.forEach((dessert) => {
       totalCountPerProduct[dessert.id] = (totalCountPerProduct[dessert.id] || 0) + 1;
    })
  }

// User Editable Region
