...and moving from javascript strings to Ruby strings is far from a "30 seconds syntactical exercise", unless you don't take into account the fact that:

* Ruby strings don't necessarily have all the same encoding

* Javascript strings don't implement all of Ruby Strings' methods

* Ruby Strings are mutable, while JS's are immutable

* R̶u̶b̶y̶ ̶d̶o̶e̶s̶n̶'̶t̶ ̶h̶a̶v̶e̶ ̶C̶h̶a̶r̶s̶,̶ ̶J̶a̶v̶a̶s̶c̶r̶i̶p̶t̶ ̶d̶o̶e̶s̶ (edit: brain fart... I probably wrote too much Clojure[script], even if char literals in cljs just yield strings again)

(Or you use Opal, which doesn't abstract Javascript Strings much)
