text = text.replace(/\s{2,}/g, ' ');
  • \s will take all spaces, including new lines, so you may change that to / {2,}/g.
  • {2,} takes two or more. Unlike \s+, this will not replace a single space with a single space. (a bit of an optimization, but it usually makes a differance)
  • Finally, the g flag is needed in JavaScript, or it will only change the first block of spaces, and not all of them.
