Hi! I've gotten an error message " Both the reduce
and filter
methods have not been called yet.", however, I didn't know what I was wrong.
I checked my chords and I confirmed "groceryTotal" was 9.47. Can you advise me how to solve this, please? Thank you!
const purchaseItems = [
{
name: 'apples',
dept: 'groceries',
price: 2.49
},
{
name: 'bread',
dept: 'groceries',
price: 2.99
},
{
name: 'batteries',
dept: 'electronics',
price: 5.80
},
{
name: 'eggs',
dept: 'groceries',
price: 3.99
},
{
name: 't-shirts',
dept: 'apparel',
price: 9.99
}
];
let groceryTotal;
// groceryTotal should be: 9.47
// Write your code below
groceryTotal = purchaseItems.filter(purchase => purchase.dept === "groceries").reduce((sum, purchase ) => sum + purchase.price, 0).toFixed(2);
