Is Javascript's array map function basically a comonadic cobind (=>> in Haskell)? Have a look as the jsmap function below.

	-- Inspired by http://nedbatchelder.com/blog/201301/stupid_languages.html
	-- which describes how the Javascript array.map function seems weird
	-- and also http://blog.sigfpe.com/2008/03/comonadic-arrays.html
	-- which describes the comonad for arrays

	import Data.Array
	import Data.Char

	class Functor w => Comonad w where
	(=>>) :: w a -> (w a -> b) -> w b
