| # --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/);
 | |
| let ourStr = "Regular expressions";
 | |
| let ourRegex = /expressions/;
 | |
| ourStr.match(ourRegex);
 | |
| ```
 | |
| 
 | |
| Here the first `match` would return `["Hello"]` and the second would return `["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 string `coding`.
 | |
| 
 | |
| # --hints--
 | |
| 
 | |
| The `result` should have the string `coding`
 | |
| 
 | |
| ```js
 | |
| assert(result.join() === 'coding');
 | |
| ```
 | |
| 
 | |
| Your regex `codingRegex` should search for the string `coding`
 | |
| 
 | |
| ```js
 | |
| assert(codingRegex.source === 'coding');
 | |
| ```
 | |
| 
 | |
| You should use the `.match()` method.
 | |
| 
 | |
| ```js
 | |
| assert(code.match(/\.match\(.*\)/));
 | |
| ```
 | |

| 
 | |
| ```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
 | |
| ```
