Here is my code:

// get "foods" array from Firebase
const foods = querySnapshot.docs.map((doc) => ({ ...doc.data() })); 
  
// loop in "foods" array and recover food's price
const fetchPrices = async () => {
  for (const food of foods) {
    const response = await fetch(`${api}/${food.id}`);
    if (!response.ok) {
      // throw error
    }
    const result = await response.json()
    food.totalPrice = food.quantity * result.market_data.current_price
  }
}
// run function
fetchPrices()

// this console.log show me initial values, without totalPrice key
console.log('foods : ', foods);

I assume that console.log() runs before the async/await function, but I don't know how to add this value in my initial array (or another).

What would be the way to add the key/value totalPrice to each elements of the "foods" array?
