Solutions/Answers:

Solution 1:

\s matches whitespace (spaces, tabs and new lines). \S is negated \s.

Solution 2:

\S matches anything but a whitespace, according to this reference.

Solution 3:

I believe it means ‘anything but a whitespace character’.

Solution 4:

/\S/.test(string) returns true if and only if there’s a non-space character in string. Tab and newline count as spaces.

Solution 5:

The \s metacharacter matches whitespace characters.
