How can I remove all extra space between words in a string literal?

some    value

Should become

some value

Also,

    This    should  become   something          else   too .

Becomes

This should become something else too .

Do not worry about moving the .. Just as above is fine. I know I can use $.trim(str) to achieve the trailing/ending space removal. But, I'm not sure how to do the 1 space between words trick.

var string =     This    should  become   something          else   too . ;

string = string.replace(/s+/g,  );

This code replaces a consecutive set of whitespace characters (s+) by a single white space. Note that a white-space character also includes tab and newlines. Replace s by a space if you only want to replace spaces.

If you also want to remove the whitespace at the beginning and end, include:

string = string.replace(/^s+|s+$/g, );

This line removes all white-space characters at the beginning (^) and end ($). The g at the end of the RegExp means: global, ie match and replace all occurences.
