JavaScript JavaScript Array Iteration Methods Combining Array Methods Combining filter() and reduce()

These JavaScript problems are difficult. Can someone tell me what I'm wrong?

Thank you in advance

app.js
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.price > 10)
    .reduce((sum, price) => sum + item.price, 0);  

Nevermind I figured it out! Thanks

Congratulations on resolving your issue!

For the benefit of other students, there are two issues in the code:

  • the filter should select items in the grocery department instead of items with a price over 10
  • the second parameter of the function in "reduce" should be named "item" instead of "price"

Thanks Steve
