Refactor challenge #2

var html = '';
var red;
var green;
var blue;
var rgbColor;

for (var cc = 0; cc!==10; cc+=1){
  function randomRgbValue (){
  return Math.floor(Math.random() * 256 );
  }
  red = randomRgbValue();
  green = randomRgbValue();
  blue = randomRgbValue();
  rgbColor = 'rgb(' + red + ',' + green + ',' + blue + ')';
  html += '<div style="background-color:' + rgbColor + '"></div>';
}

document.write(html);

Looks good! My only suggestion would be to put the randomRgbValue() function outside of the for loop so it is not recreated on every iteration.
