JavaScript Create an Array of Objects

I need clarification on the totalValue function.

From the workspace instructions and video, as I understood it, Dave wants us to get the total value of all products in the array. Doesn't the code in the solution only calculate the total price of inventory for that item, not for the full array?

Here is the code I have for calculating the totalValue of all items in the product array.

function totalValue(arr) {
  let totalPrice = 0;
  for (let i=0; i < arr.length; i++) {
    let inventoryPrice = arr[i].inventory * arr[i].unit_price
    totalPrice += inventoryPrice
  }
  return totalPrice.toFixed(2);
}

Other than the creation of an intermediate variable, this is essentially the same as the solution shown in the "Teacher's Notes" section of the page below the video. But the addition of the ".toFixed(2)" is a nice touch. :+1:

Initially when reading the teachers solution, I was reading his code as only getting the price of the individual items. After looking again I realize that you are correct.
