My solution for the Refactor Challenge

Got it down to 8 lines of code excluding spaces

let html = '';
let randomRGB;
let randomValue = () => Math.floor(Math.random() * 256);

for(i=0; i<=10; i++){
  randomRGB = `rgb( ${randomValue()}, ${randomValue()}, ${randomValue()} )`;
  html += `<div style="background-color: ${randomRGB}">${i}</div>`;
}

document.querySelector('main').innerHTML = html;

Good job! :+1:
And if you convert randomRGB into a function, you can initialize it when you declare it, and save another line:

let html = '';
let randomRGB = () => `rgb(${randomValue()}, ${randomValue()}, ${randomValue()})`;
let randomValue = () => Math.floor(Math.random() * 256);

for (i = 0; i <= 10; i++) {
  html += `<div style="background-color: ${randomRGB()}">${i}</div>`;
}

document.querySelector('main').innerHTML = html;
