# --description--

這些動畫開始看起來很酷，但是有時可能會讓用戶分心。

請刪除 `document ready function` 內的三個 jQuery 函數，但保留 `document ready function` 本身。

# --hints--

應該刪除 `document ready function` 中的三個 jQuery 函數。

```js
assert(code.match(/\{\s*\}\);/g));
```

應該保持 `script` 標籤不變。

```js
assert(code.match(/<script>/g));
```

應該保持 `$(document).ready(function() {` 在 `script` 標籤的開頭不變。

```js
assert(code.match(/\$\(document\)\.ready\(function\(\)\s?\{/g));
```

應該保持 `document.ready` function 用 `})` 閉合。

```js
assert(code.match(/.*\s*\}\);/g));
```

應該保持 `script` 標籤閉合。

```js
assert(
  code.match(/<\/script>/g) &&
    code.match(/<script/g) &&
    code.match(/<\/script>/g).length === code.match(/<script/g).length
);
```
