Wondering if this solution also makes sense?

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;

For future questions, take a look at these videos about using Markdown formatting to preserve the code's appearance, and sharing a snapshot of your workspace.

But after guessing about the formatting, these issues are still apparent:

  • you can't define a variable twice (first let randomRGB; and later const 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.
