Match Whitespace

Problem Explanation

To finish this challenge, it's necessary to use the /s character class in your regexp pattern.

\s matches a single white space character. (including space, tab, form feed, line feed and other Unicode spaces.

For example:

/\s\w*/;
// matches " bar" in "foo bar".

important: Characters are case sensitive in regexp. \S matches a single character other than white space.
