Answer 1

You can use split and add a wordcounter to the String prototype:

String.prototype.countWords = function(){
  return this.split(/\s+/).length;
}

'this string has five words'.countWords(); //=> 5

If you want to exclude things like ... or - in a sentence:

String.prototype.countWords = function(){
  return this.split(/\s+\b/).length;
}

'this string has seven ... words  - and counting'.countWords(); //=> 7
