Any way I can make my code shorter?

Is there any way I can make it better?

let html = '';

const randomValue = () => Math.floor(Math.random() * 256);

const randomRGB = (value) => rgb( ${value()}, ${value()}, ${value()} );

for ( let i = 1; i <= 10; i++ ) { html += <div style="background-color: ${randomRGB(randomValue)}">${i}</div>; }

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

When posting code, always use Markdown formatting to preserve the code's appearance and retain special symbols (such as the ` accent mark).

But shorter isn't always "better". There's a value in having code that's easily readable, and over-optimizing and abbreviating can compromise that. This sample seems pretty concise as is, not much could be reduced and still have it easy to read.
