Both the
reduce
andfilter
methods have not been called yet.
here is my code:
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,item) => {
return total += item.price;
}, 0).toFixed(2);

is causing the issue by converting the result into a string. It wasn't part of the instructions, and the validator is expecting groceryTotal
to be a number.

5,523 Pointsthanks, removed and it worked..
but the comment says the price should be "9.47" so I prefixed it to 2. Also we learned how to prefix in the previous video in the module so I thought it was necessary.
