## 匹配通配符期间的任何内容
|
|||
|
|
|
|||
|
|
## 提示1：
|
|||
|
|
|
|||
|
|
点`.`是这一挑战的关键。
|
|||
|
|
|
|||
|
|
## 提示2：
|
|||
|
|
|
|||
|
|
你应该把点放在正确的位置。
|
|||
|
|
|
|||
|
|
## 解
|
|||
|
|
|
|||
|
|
```javascript
|
|||
|
|
let exampleStr = "Let's have fun with regular expressions!";
|
|||
|
|
let unRegex = /.un/; // Change this line
|
|||
|
|
let result = unRegex.test(exampleStr);
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 释
|
|||
|
|
|
|||
|
|
这段时期`.`将是任何一个字符，因此字符串“run”，“sun”，“fun”和“pun”具有相同的un charaters。
