```jsx
const squares = [null, null, null, null, null, null, null, null, null];
squares[0] = 'X';
// Now `squares` is ["X", null, null, null, null, null, null, null, null];
// 이제 `squares`는 `["X", null, null, null, null, null, null, null, null]`입니다.
```

그리고 아래는 `squares` 배열을 변형하지 않고 데이터를 변경한 경우의 모습입니다.

```jsx
const squares = [null, null, null, null, null, null, null, null, null];
const nextSquares = ['X', null, null, null, null, null, null, null, null];
// Now `squares` is unchanged, but `nextSquares` first element is 'X' rather than `null`
// 이제 `squares`는 변경되지 않았지만 `nextSquares`의 첫 번째 요소는 `null`이 아닌 `'X'`입니다.
```

최종 결과는 같지만, 원본 데이터를 직접 변형하지 않음으로써 몇 가지 이점을 얻을 수 있습니다.
