# --description--
|
|
|
|
JavaScript allows the use of both single (`'`) and double (`"`) 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
|
|
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.';
|
|
```
|
|
|
|
The first two are correct, but the third is incorrect.
|
|
|
|
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
|
|
const allSameQuotes = 'I\'ve had a perfectly wonderful evening, but this wasn\'t it.';
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
Fix the string so it either uses different quotes for the `href` value, or escape the existing ones. Keep the double quote marks around the entire string.
|
|
|
|
# --hints--
|
|
|
|
Your code should fix the quotes around the `href` value `#Home` by either changing or escaping them.
|
|
|
|
```js
|
|
assert(code.match(/<a href=\s*?('|\\")#Home\1\s*?>/g));
|
|
```
|
|
|
|
Your code should keep the double quotes around the entire string.
|
|
|
|
```js
|
|
assert(code.match(/"<p>.*?<\/p>";/g));
|
|
```

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);
