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:

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:
