Can this regular expression work for the password validation portion? /[^\s]+$/

That regular expression will match anything that does not have a whitespace at the end of the string.

Full Stack JavaScript Techdegree Graduate 29,854 PointsSorry about that. I thought the question ties to the video I watched when I click the 'help' button. My question was tied to the 'Validating a Password' video in the 'Regular Expressions in JavaScript' course. Joel used the following lookaround: /^(?=.\d)(?=.[a-z])(?=.[A-Z]).$/
but was wondering if the follow could be used to validated a password (with lowercase, uppercase, and numbers only)? /[^\s]+$/
if not, what would be the best regex expression besides the lookaround Joel uses?

11,835 PointsThe problem with that solution is that it doesn't verify it has all of the required symbols.
It only checks if it DOESN'T have a space, but beyond that, anything goes.
I think a lookaround is pretty much the best way to do it, I wouldn't know of another efficient way to do that and to make sure it has all of the symbols you want it to have.
