Best use << for string concatenation inside reduce loop. Using += will create a new object for each iteration.

@JoanaB Yeah, tr is often overlooked - even though it's actually old as dirt: Its name comes from a standard unix/linux command line program also called tr. Don't know when the CLI program appeared but I'm guessing ~40 years ago

@JoanaB Yeah, regular expressions are incredibly useful, though in this case String#tr does the job just as well, without the (admittedly negligible) overhead of regex. Replacing characters in a string is precisely what tr is built for; using regex is pretty overkill
