Here is my perspective: There are plenty of reasons to use the same language on FE and BE but for me the main problem is the JS standard library. Let me give you one example: Lets say you want to validate if a string is a valid URL. What is a good way to do this in JS? Just for reference in Ruby for example I can do: URI.parse(input).kind_of?(URI::HTTP) No gems or any other engines needed.
