|
## Hint 1:
|
||
|
The dot `.` is the key in this challenge.
|
||
|
|
||
|
## Hint 2:
|
||
|
You should put the dot on the right position.
|
||
|
|
||
|
## Solution
|
||
|
```javascript
|
||
|
let exampleStr = "Let's have fun with regular expressions!";
|
||
|
let unRegex = /.un/; // Change this line
|
||
|
let result = unRegex.test(exampleStr);
|
||
|
```
|
||
|
## Explaination
|
||
|
The period `.` will be any one character so the strings "run", "sun", "fun" and "pun" have the same un charaters.
