# --description--

So far, you have only been checking if a pattern exists or not within a string. You can also extract the actual matches you found with the `.match()` method.

To use the `.match()` method, apply the method on a string and pass in the regex inside the parentheses.

Here's an example:

```js
"Hello, World!".match(/Hello/);
// Returns ["Hello"]
let ourStr = "Regular expressions";
let ourRegex = /expressions/;
ourStr.match(ourRegex);
// Returns ["expressions"]
```

Note that the `.match` syntax is the "opposite" of the `.test` method you have been using thus far:

```js
'string'.match(/regex/);
/regex/.test('string');
```

# --instructions--

Apply the `.match()` method to extract the word `coding`.

# --hints--

The `result` should have the word `coding`

```js
assert(result.join() === 'coding');
```

Your regex `codingRegex` should search for `coding`

```js
assert(codingRegex.source === 'coding');
```

You should use the `.match()` method.

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

# --seed--

## --seed-contents--

```js
let extractStr = "Extract the word 'coding' from this string.";
let codingRegex = /change/; // Change this line
let result = extractStr; // Change this line
```

# --solutions--

```js
let extractStr = "Extract the word 'coding' from this string.";
let codingRegex = /coding/; // Change this line
let result = extractStr.match(codingRegex); // Change this line
```
