When was that? Dart started out generating massive JavaScript files, but the output has been significantly reduced in the past couple of years (something to do with using transformers to replace some of the reflection at transpilation time, I think).

About half a year ago. It turned 1500 lines of Dart into ~10000 lines of Javascript. That might not be that much to handle for a webview but it was quite hard to debug. I used it as a UserScript in WKWebView so I couldn't use DartEditor. In comparison, the haxe code, which looked very similar to the Dart code, was compiled into 1400 lines of pretty readable Javascript.
