Code Execution Issue

Hello. I've written the code exactly as you show in the video, but the browser is giving me a runtime error. Could this have something to do with my browser? I live in Spain.

My code is:

let html = '';

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

function randomRGB (value) { const color = rgb( ${value()},${value()},${value()} ); return color;

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

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

And the console error is: Uncaught SyntaxError: Unexpected end of input (script.js:13)

Maybe there is an error in the code that I'm not able to see.

Thanks for your help.

Best regards.

Hello Isabel,

It appears that your code is missing an ending curly brace in your randomRGB function, directly after the return color; statement. This is a common mistake that even experienced programmers make. Don't fret; there are tools to help you catch these errors. For instance, in VSCode with linting enabled, you can have it automatically detect and flag missing braces.

Furthermore, consider wrapping your code in triple backticks (`) when posting it. This makes the code more readable and easier to spot issues like missing braces.

I hope this helps. Happy coding!
