Debug this JavaScript function and explain the bug:

function addPrices(items) {
  return items.reduce((sum, item) => {
    sum + item.price;
  }, 0);
}

Input:
[{ price: 10 }, { price: 15 }, { price: 5 }]

Expected result: 30
Actual result: undefined

User intent:
Debug this broken JavaScript function and explain the fix clearly.
Output preview
The bug is here:

```js
return items.reduce((sum, item) => {
    sum + item.price;   // !!!
}, 0);
```

### What happens

- The arrow function has a *block body* (`{ ... }`), so the last expression is *not* automatically returned.
- `sum + item.price;` evaluates the number but throws the result away.
- The callback therefore returns `undefined` on every iteration.
- `reduce` ends up returning `undefined`, which is what you see.

### The fix

Return the new accumulator each time:

```js
return it…
