Getting Error : Unescaped '-' in jshint [closed]

Answer 1

var string = (/[^\u0041-\u005A\u0061-\u007A\u00C0-\u00F6\u00F8-\u00FF\-\s]/gi);

\s is a set of characters so you can't do a range to it, meaning the -\s doesn't make sense, and hence the error.

Answer 2

It's just a hint. Likely you want that hyphen. Yet the last one, in the "range" -\s, it seems to be invalid. Are you sure you don't want to omit it, and just match \s? If not, better escape it with a backslash as it's in the middle of a character class.
