Front End Web Development Techdegree Student 10,337 PointsWhy am i getting the 'Bummer: Both the `reduce` and `filter` methods have not been called yet.' ERROR?
I tested my code in the console and it worked by getting the result 9.47, but when i try to check the exercise it send me the error "Bummer: Both the reduce and filter methods have not been called yet" and i dont know why. I used the code below:
groceryTotal = purchaseItems .filter(item => item.dept === 'groceries') .reduce((total, itemPrice) => total + itemPrice.price, 0).toFixed(2);
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(item => item.dept === 'groceries')
.reduce((total, itemPrice) => total + itemPrice.price, 0).toFixed(2);

Treehouse Project ReviewerHi there Ravel Oliveira 👋
I was toying around with your code for a bit and realized it was the .toFixed(2) being added to the end that was throwing the whole thing off. After removing that your code worked perfectly
groceryTotal = purchaseItems
.filter(item => item.dept === 'groceries')
.reduce((total, itemPrice) => total + itemPrice.price, 0);
Unfortunately, it seems it's another scenario where a simple addition of something (or sometimes a lack of something) was triggering the failure, but the error message provided was not helpful in that scenario. Sorry for that inconvenience!
Nice work!
