Javascript - How to remove all extra spacing between words

Question

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

\"some    value\"

Should become

\"some value\"
<         


        

Answer 1

var str = "    This    should  become   something          else   too . "
$.trim(str).replace(/\s(?=\s)/g,'')

This uses lookahead to replace multiple spaces with a single space.
