How to prevent spaces in a regular expression?

Question

Regular Expressions

Hello.
In general, you need to test a string with a regular expression for:
1. Length 6-16
2. At least 1 uppercase character
2. At least 1 lowercase character
3. At least 1 digit
4. Optional special characters.
this is what I came up with:

/(?=^.{8,16}$)((?=.*\d)|(?=.*\W+))(?![.\n])(?=.*[A-Z])(?=.*[a-z]).*$/

But this regex will skip spaces...

Answer 1

Spaces prevent this [^\s]
