Hi, here's my solution. Feedback would be appreciated

let html = '';

function createColorPad(c=0, r=Math.floor(Math.random() * 256),g=Math.floor(Math.random() * 256),b=Math.floor(Math.random() * 256)) {
  return `<div style="background-color: rgb(${r}, ${g}, ${b})">${c}</div>`;
}

for (i=1; i<=10; i++) {
  html += createColorPad(i);
}

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

thanks for reading, happy coding

Using parameters with default values is clever; but unless you're sure the function will need to be called with explicit arguments, a more conventional approach using assignments in the code body might produce easier-to-read code.

As it is, you could enhance readability by placing the complex argument expressions on separate lines:

function createColorPad(
  c = 0,
  r = Math.floor(Math.random() * 256),
  g = Math.floor(Math.random() * 256),
  b = Math.floor(Math.random() * 256)
) {

But kudos for creativity!   :+1:

Thank you Steven, I really forgot to take readability into account 😔
