> It doesn't actually mater what language you learn first OK, start with Prolog. Now move to Ruby. Then Haskell, and include some SQL in that as well, somehow. Now write me a program in APL. Languages within the same paradigm are mostly similar. But there are a lot of paradigms, and some concepts don't transfer well at all. (Quick, what's the equivalent of an anonymous inner class in Prolog?) |

...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)
