Dart had a lot of problems, most notably that GC between JS and Dart was never handled well, because the Dart VM and V8 used separate garbage collectors. Besides, I'd much rather have the effort go into one new VM (or VM "mode"), so we can solve the problem once and for all. That is, let's have Web Assembly.
