# --description--
JavaScript 允許使用單引號(`'`)和雙引號(`"`)聲明字符串。 決定使用哪一個通常看個人偏好,但有一些例外。
如果字符串中有縮寫或存在一段帶引號的文本,你就會明白爲什麼 JavaScript 允許兩種引號了。 請注意,不要提前用引號結束字符串,這會導致語法錯誤。
下面是混合使用引號的一些示例:
```js
const grouchoContraction = "I've had a perfectly wonderful evening, but this wasn't it.";
const quoteInString = "Groucho Marx once said 'Quote me as saying I was mis-quoted.'";
const uhOhGroucho = 'I've had a perfectly wonderful evening, but this wasn't it.';
```
前兩項是正確的,但第三項是不正確的。
當然,只使用一種引號也是可以的。 可以使用反斜槓(`\`)來轉義字符串內的引號:
```js
const allSameQuotes = 'I\'ve had a perfectly wonderful evening, but this wasn\'t it.';
```
# --instructions--
修復字符串,使其對 `href` 值使用不同的引號,或者轉義現有的引號。 在整個字符串周圍保留雙引號。
# --hints--
你應通過更改或轉義來修復 `href` 的值 `#Home` 周圍的引號。
```js
assert(code.match(/<a href=\s*?('|\\")#Home\1\s*?>/g));
```
你應該在整個字符串外圍保留雙引號。
```js
assert(code.match(/"<p>.*?<\/p>";/g));
```
# --seed--
## --seed-contents--
```js
let innerHtml = "<p>Click here to <a href="#Home">return home</a></p>";
console.log(innerHtml);
```
# --solutions--
```js
let innerHtml = "<p>Click here to <a href=\"#Home\">return home</a></p>";
console.log(innerHtml);
```
