title: Catch Mixed Usage of Single and Double Quotes

## Description
<section id='description'>
JavaScript allows the use of both single (<code>'</code>) and double (<code>"</code>) quotes to declare a string. Deciding which one to use generally comes down to personal preference, with some exceptions.
Having two choices is great when a string has contractions or another piece of text that's in quotes. Just be careful that you don't close the string too early, which causes a syntax error.
Here are some examples of mixing quotes:

```js
// These are correct:
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.'";
// This is incorrect:
const uhOhGroucho = 'I've had a perfectly wonderful evening, but this wasn't it.';
```

Of course, it is okay to use only one style of quotes. You can escape the quotes inside the string by using the backslash (\) escape character:

```js
// Correct use of same quotes:
const allSameQuotes = 'I\'ve had a perfectly wonderful evening, but this wasn\'t it.';
```

## Instructions
<section id='instructions'>
Fix the string so it either uses different quotes for the <code>href</code> value, or escape the existing ones. Keep the double quote marks around the entire string.

## Tests

```yml
tests:
  - text: Your code should fix the quotes around the <code>href</code> value "#Home" by either changing or escaping them.
    testString: assert(code.match(/<a href=\s*?('|\\")#Home\1\s*?>/g));
  - text: Your code should keep the double quotes around the entire string.
    testString: assert(code.match(/"<p>.*?<\/p>";/g));

```
