Will Dart support the use of existing JavaScript libraries?

Question

I understand Dart compiles to JavaScript, and I read the Dart Language Spec on Libraries, although I didn\'t see an answer there. Also a search on their discussion form for

There is now a new simpler way https://pub.dartlang.org/packages/js (currently version 0.6.0-beta.6)

Make JS classes and functions available to Dart like:

@JS("JSON.stringify")
external String stringify(obj);

@JS('google.maps')
library maps;

// Invokes the JavaScript getter `google.maps.map`.
external Map get map;

// `new Map` invokes JavaScript `new google.maps.Map(location)`
@JS()
class Map {
  external Map(Location location);
  external Location getLocation();
}

// `new Location(...)` invokes JavaScript `new google.maps.LatLng(...)`
//
// We recommend against using custom JavaScript names whenever
// possible. It is easier for users if the JavaScript names and Dart names
// are consistent.
@JS("LatLng")
class Location {
  external Location(num lat, num lng);
}
