My JavaScript solution, which would look a lot nicer if the TC39 finally added a pipeline operator.

const checkRange = num => Math.min(255, Math.max(num, 0))

const rgb = (...args) => args.slice(0, 3)
    .map(x => checkRange(x)
        .toString(16)
        .toUpperCase()
        .padStart(2, '0'))
    .join('')

We have padStart now in strings to add characters to the beginning up to a certain length.

String.prototype.padStart would handle the addZeroes trick for you. ;)

I got really confused when the link opened in Portuguese. I had to check my VPN 😆

Whoops! Sorry about that. :P Should be fixed now.

I've modified it to use padStart instead of my custom function.

Thanks @lffg and @avalander !
