JavaScript JavaScript Loops, Arrays and Objects Simplify Repetitive Tasks with Loops The Refactor Challenge, Part 2

I would like you guys to review my code, i'm sure i'll get helpful feedback

My solution has 10 lines. I tried my best to DRY it.

function randomColor() {
 function color() {
 return Math.floor(Math.random() * 256 );
 }
 var rgbColor = 'rgb(' + color() + ',' + color() + ',' + color() + ')';
 return '<div style="background-color:' + rgbColor + '"></div>'; 
}
for (var i= 0; i < 10; i +=1) {
  document.write(randomColor());
}

Note that this code won't create the HTML required to display the colored dots, it will just print the text value of the 10 colors, like rgb(123, 45, 67).

function color() {

}
function randomColor() {
 return 'rgb(' + color() + ',' + color() + ',' + color() + ')';
}
for (var i= 0; i < 10; i++) {
  document.write(randomColor());
}

I just removed one line and the errors in your code. Hope it'll be the best solution to your answer.
