## Description
到目前为止，您只是检查字符串中是否存在模式。您还可以使用.match()方法提取您找到的实际匹配项。要使用.match()方法，请将该方法应用于字符串并传入括号内的正则表达式。这是一个例子： “你好，世界！”。匹配（/ Hello /）;
//返回[“Hello”]
让ourStr =“正则表达式”;
让ourRegex = / expressions /;
ourStr.match（ourRegex）;
//返回[“表达式”]
## Instructions
应用.match()方法来提取单词coding 。
## Tests
```yml
tests:
- text: result应该有单词coding
testString: 'assert(result.join() === "coding", "The result should have the word coding");'
- text: 你的regex codingRegex应该搜索coding
testString: 'assert(codingRegex.source === "coding", "Your regex codingRegex should search for coding");'
- text: 您应该使用.match()方法。
testString: 'assert(code.match(/\.match\(.*\)/), "You should use the .match() method.");'
```
## Challenge Seed
```js
let extractStr = "Extract the word 'coding' from this string.";
let codingRegex = /change/; // Change this line
let result = extractStr; // Change this line
```
