This is my problem:

console.log("    $".match("/^/s{4}\$/"));

This produces "null!". I thought the string backslash might need to be doubled, so I tried this:

console.log("    $".match("/^/s{4}\\$/"));

"null" also. Clearly, there's something I'm missing (my alopecia is acting up).

Thanks in advance.

Two things:

1. When using regular expressions, it's best to use RE literals versus strings when you can. That way you get syntax checking, and avoid string escaping woes.

2. \s

Yours works, but I need the string version of the regular expression, which is causing me grief.
