RGBToHex

Converts the values of RGB components to a colorcode.

Convert given RGB parameters to hexadecimal string using bitwise left-shift operator (<<) and toString(16), then padStart(6,'0') to get a 6-digit hexadecimal value.

const RGBToHex = (r, g, b) => ((r << 16) + (g << 8) + b).toString(16).padStart(6, '0');
// RGBToHex(255, 165, 1) -> 'ffa501'
