Even the original, untyped, Dart was designed to be easier to optimize that JavaScript (e.g. it's class based, not prototype based, so the runtime doesn't have t work as much to optimize object access).

Recently Dart has added a strong mode (https://github.com/dart-archive/dev_compiler/blob/master/STR..., http://news.dartlang.org/2017/01/sound-dart-and-strong-mode....).

One of the reasons for strong mode is to enable better optimizations (https://www.dartlang.org/guides/language/sound-faq#why-stron...).

I'm going to save these links for the next time I get downvoted for saying that js object system and dynamic typing suck for performance :).

When JS performance threads come up I always mention that JS will never be as fast as Go/Java. Some people have a tantrum when I explain these issues. The sources I usually cite are dense and people just continue to downvote without reading them.
