let html = '';
let red;
let green;
let blue;
let randomRGB;
const randomValue = () => Math.floor (Math.random() * 256);
const randomRGB = rgb( ${randomValue()}, ${randomValue()}, ${randomValue()} )
;
for (let i = 0, i < 10, i++){
red = randomValue ();
green = randomValue();
blue = randomValue();
randomRGB;
html += <div style="background-color: ${randomRGB}">${i}</div>
;
}
document.querySelector('main').innerHTML = html;

But after guessing about the formatting, these issues are still apparent:
- you can't define a variable twice (first
let randomRGB;
and laterconst randomRGB ...
) - creating the color outside the loop will cause every created element to have the same color
- the separators between clauses in a "for" loop must be semicolons, not commas
- referencing a string as its own statement (
randomRGB;
) doesn't cause any action
TIP: A little experimentation in the workspace will help you find issues like these.
