Random Color Strings

  1. R = Math.random
  2. b = document.body
  3. b.style = 'background: black; font-family: sans-serif; text-transform: uppercase; color: white;'
  4.  
  5. setInterval(_ => {
  6.   if (R()<.9) {
  7.     s = ''
  8.     for(i=0;i<R() * 30 + 4;i++) s+=(~~(R() * 0xff)).toString(36)
  9.       .replace(R() < .9 ? /[0-9]/g : '', '')

  13.   }
  14. }, 100)

Make some random strings and give them a random color… a friend of mine showed a work in progress forked codepen – so I created a golfed version/variation…
