Replace multiple whitespaces with single whitespace in JavaScript string

I have used trim function to remove the white spaces at the beginning and end of the sentences. If there is to much white spaces in between words in a sentence, is there any method to trim?

for example

"abc                  def. fds                            sdff."

try

abc                  def. fds                            sdff.

 .replace(/s+/g,' ')

or

abc                  def. fds                            sdff.

     .split(/s+/)

     .join(' ');

or use this allTrim String extension

String.prototype.allTrim = String.prototype.allTrim ||

     function(){

        return this.replace(/s+/g,' ')

                   .replace(/^s+|s+$/,'');

     };

//usage:

alert(' too much whitespace     here   right?  '.allTrim());

   //=> too much whitespace here right?
