4{-|This library does basic conversions between Elm and JS values. This allows
5the internal data structures of Elm to change and improve with no impact on JS
6integration.
8It is intended to be imported as `import JavaScript as JS`. That way functions
9like `JS.toInt` convert JavaScript *to* Elm integers and functions like
10`JS.fromString` gets JavaScript *from* Elm strings.
