What does /\S/ mean in a regex?

while (cur ! = null) { if (cur.nodeType == 3 && ! /\S/. test(cur.nodeValue)) { element. removeChild(cur); } else if (cur. nodeType == 1) { cleanWhitespace(cur); }
}

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

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

I believe it means 'anything but a whitespace character'.

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

The \s metacharacter matches whitespace characters.
