The Dart to JavaScript compiler that reads a Dart file and translates it to JavaScript.

The Dart to JavaScript compiler that reads a Draft file and translates it to JavaScript. It generates JavaScript source code from the Draft files. The name of the tool used to compile the code is draft2js. Dart Editor uses dart2js behind the scenes whenever Dart Editor compiles to JavaScript. It produces a file that contains the JavaScript equivalent of the Dart code. It also produces a source map, which can help to debug the JavaScript version of the app more easily.
