Spot the mistake updating this mystery prize label.

```js
const prizeBox = document.querySelector("#prize-box");
const newBadge = document.createElement("span");
newBadge.textContent = "⭐ Golden Turnip";
prizeBox.appendChild = newBadge;

```

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

The `appendChild` method is being incorrectly assigned as a property instead of being called as a function. It should be `prizeBox.appendChild(newBadge);` to add the new element.
