The V8 that Dart is compared against is always the latest, and includes Crankshaft which came out 4 years ago.

Dart VM uses a black list for methods that cannot be optimized by VM intelligence. I cannot say anything about V8. But with optimization in Dart VM not all so good. Dynamic typing in Javascript is a normal behavior (VM optimized for that). Dynamic typing in Dart produce a lot of pitfalls (in the sense of the intelligence of optimization).
