This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# String.tr_s (from ruby core) --- str.tr_s(from_str, to_str) -> new_str --- Processes a copy of *str* as described under String#tr, then removes duplicate characters in regions that were affected by the translation. "hello".tr_s('l', 'r') #=> "hero" "hello".tr_s('el', '*') #=> "h*o" "hello".tr_s('el', 'hx') #=> "hhxo"
