is-string-and-not-blank
Version:
3x as fast as `is-whitespace` and `whitespace-regex` thanks to `is-string-blank`. This package is a simple function that accepts an argument and returns `true` if it is a string AND it is not blank. Supports Node and Browser environments.

/**
* Is this string all whitespace?
* This solution kind of makes my brain hurt, but it's significantly faster
* than !str.trim() or any other solution I could find.
*
* whitespace codes from: http://en.wikipedia.org/wiki/Whitespace_character
* and verified with:
*
* for(var i = 0; i < 65536; i++) {
* var s = String.fromCharCode(i);
* if(+s===0 && !s.trim()) console.log(i, s);
* }
*
* which counts a couple of these as *not* whitespace, but finds nothing else
* that *is* whitespace. Note that charCodeAt stops at 16 bits, but it appears
* that there are no whitespace characters above this, and code points above
* this do not map onto white space characters.
