Input only 3 characters and 3 asterisk

Question

I need to program my code to only let users input 3 asterisk or 3 alphabets. The 2 different characters can't be used together. How can I do that?

For instance, user can input *** or AAA

I looked up some stuff on here and all I got was regEx = \d{3}[a-zA-Z]{3}$/;

This did not work for me.

The regex will simply be ***|[A-Za-z]{3} if you want exactly 3 asterisks or 3 letters. — Mark Madej, Oct 22 '17 at 15:31
If there are only two options, then why not use radio buttons? — Michael Benjamin, Oct 22 '17 at 15:32
Michael_B the input can be any combination of alphabets but as for asterisk user can only input 3 asterisks. — Tink89, Oct 22 '17 at 15:48
Maybe you can use [this regex](https://regex101.com/r/apm5gU/1) `^(?:\*{3}|[A-Za-z]{3})$` — The fourth bird, Oct 22 '17 at 15:58

You can use this regex:

^(?:\*{3}|[A-Za-z]{3})$

Between the beginning of the string ^ and the end of the string$, you can specify 3 times an * \*{3} or | 3 times [A-Za-z]{3}.
