Language.Javascript.JSaddle.Classes
Description
These classes are used to make various JavaScript types out of whatever we have. Functions in jsaddle take these as inputs. This alows implicit casting and eager evaluation.
Synopsis

- fromJSValUnchecked :: JSVal -> JSM a
- fromJSValListOf :: JSVal -> JSM (Maybe [a])
- fromJSValUncheckedListOf :: JSVal -> JSM [a]
- class ToJSVal a => ToJSString a where
- toJSString :: a -> JSString
- class FromJSVal a => FromJSString a where
