Also, Nothing is also returned for values out of range. They are not silently truncated. (Except for Float where there may be loss of precision) during conversion.The reason for this class is because GHCJS.Marshal.fromJSVal and GHCJS.Marshal.pFromJSVal are not safe to use as it assumes that the JSVal are of the correct type and not null. (https:/ github.comghcjs ghcjs-base}issues/87). The safe way to convert from JSVal is to use JavaScript.Cast or to use the 'Maybe a' instance of FromJSVal, ie *fromJSVal :: JSVal -> IO (Maybe (Maybe a)), which is a bit more awkward to use. Also, Javascript.Cast doesn't have much instances, and it hardcodes the instance detection method to javascript  isinstance4 which is not sufficient for complex types (https:/ github.comghcjs ghcjs-base issues/86).~This is an IO because since JSVal is mutable, this function may different results for the same JSVal at later points in time.This provides a consistent way to convert to JSVal, with different semantics for Char. In the Char's instance of ToJS, it converts to a string instead of integer - IMHO this is less surprising.The other reason for this class is while GHCJS base provide both IsJSVal and PToJSVal to convert to jsval, some types are instances of one or the other class. This means you can't use the "Maybe a" instance of PToJSVal if it contains IsISJVal but not pToJSVal.hThis is a pure conversion, so instances must be able to convert the same or equivalent JSVal each time.3This will only succeed on a single character string$ Char instance converts to string4456789:;  !"#$%&'()*+2456789:;  !"#$%&'()*+None,This makes it easier to use OverloadedStrings with inputs that accept a JSVal that could be a JSString Less verbose version of'toJS @JSString'-This makes it easier to use OverloadedStrings with inputs that accept a JSVal that could be a Data.Text Less verbose version of'toJS @Text'.This makes it easier to use OverloadedStrings with inputs that accept a JSVal that could be a [String] Less verbose version of'toJS @Jtring',-.,-.,-.,-.None0\get a property of any JSVal.
