As a former JS-head and newly-Flutter/Dart-head, this is certainly a step forward for JS frameworks.
However, one thing notably absent from the page and a quick Google search are layout animations. React-Native has this in the (poorly-supported and almost-niche) form of LayoutAnimation, however support is notably missing in React-Native-Web and other frameworks attempting to bring true cross-platform support.
As for me (not that anyone cares), this is a very cool advancement, but doesn't change many of the complaints against the current (and numerous) set of issues with JS, and will be sticking with Flutter.
