{-|This library does basic conversions between Elm and JS values. This allows
the internal data structures of Elm to change and improve with no impact on JS
integration.

It is intended to be imported as `import JavaScript as JS`. That way functions
like `JS.toInt` convert JavaScript *to* Elm integers and functions like
`JS.fromString` gets JavaScript *from* Elm strings.
