Object bug, one line off.

```js
const card = { width: 320, height: 180 };
const { widht, height } = card;

console.log(widht * height);

```

Reply with what is broken and how you would fix it.

**Spot the Bug answer:** A typo exists in the destructuring assignment for the ‘width’ property.

**The fix:**  
Change ‘widht’ to ‘width’ in the destructuring assignment.

**Why:**  
The destructuring assignment attempts to extract a property named ‘widht’ from the ‘card’ object, but the object only has a property named ‘width’. This results in ‘widht’ being undefined, leading to a NaN (Not a Number) result when multiplied by ‘height’.

lol “widht” is such a classic. I’ve definitely shipped stuff like that before.

It’s always the tiny things that get you.
