I'm been experimenting with UHC's js backend. One of the things that struck me was that in Haskell if I have a function like: forever :: Monad m => m a -> m a I can use it for either asynchronous or synchronous javascript, e.g forever :: IO a -> IO a forever :: ContT r IO a -> ContT r IO a The same function can take a synchronous js function or an async js function and run it in an infinite loop. For this reason, I think that if you want to learn from Haskell in writing reusable js then you should look into monads.
