# --description--

Sometimes whitespace characters around strings are not wanted but are there. Typical processing of strings is to remove the whitespace at the start and end of it.

# --instructions--

Write a regex and use the appropriate string methods to remove whitespace at the beginning and end of strings.

**Note:** The `String.prototype.trim()` method would work here, but you'll need to complete this challenge using regular expressions.

# --hints--

`result` should equal to `"Hello, World!"`

```js
assert(result == 'Hello, World!');
```

Your solution should not use the `String.prototype.trim()` method.

```js
assert(!code.match(/\.?[\s\S]*?trim/));
```

The `result` variable should not be set equal to a string.

```js
assert(!code.match(/result\s*=\s*".*?"/));
```

# --seed--

## --seed-contents--

```js
let hello = "   Hello, World!  ";
let wsRegex = /change/; // Change this line
let result = hello; // Change this line
```

# --solutions--

```js
let hello = "   Hello, World!  ";
let wsRegex = /^(\s+)(.+[^\s])(\s+)$/;
let result = hello.replace(wsRegex, '$2');
```
