|  | ## Match Anything with Wildcard Period
 | ||
|  | <!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds  --> | ||
|  | 
 | ||
|  | ## 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. | ||
