Dart2JS is the Dart-to-JavaScript compiler for Dart. This compiler will provide high-quality translation from Dart to JavaScript. Some areas that will explored in this project are: * high-performance extensible scanner and parser * concrete type inferencing * fancy language tool support * programming environment integration * SSA-based intermediate representation * adaptive compilation on the client
