It works by using a regular expression to get each digit inside the rgb string, slice(1) to get only the digits (the first result of match is the full string itself), map to iterate through each digit, each iteration converting to Number with parseInt, then back to an hexadecimal String (through a base-16 conversion), adding zero if needed via padStart.
