Converts the values of RGB components to a hexadecimal color code.

• Convert given RGB parameters to hexadecimal string using bitwise left-shift operator (<<) and Number.prototype.toString().
• Use String.prototype.padStart() 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'
