More recent benchmarks[1] show 85-91%. IME developer productivity has been far more important than raw performance. Not sure where the fading away perception is coming from; looks like it's still trending up, or at least staying afloat. [2] Some barriers to entry: * still have to interface with old javascript libraries for anything not ported to Dart * compilation step + debugging. I know there's probably a sourcemap, but that's still more friction than straight javascript. * learning curve * pioneers get arrows in their back. Everything new has gotchas people haven't found yet. Javascript has some really shitty corners, but we know all about them. Dart's pros have to outweigh these. I've only toyed with it, and from a strictly language-vs-language I like it better than javascript. If it gains traction, it'll start with toy projects -> company intranets -> the occasional startup -> small company, etc. [1] https://www.dartlang.org/performance/ https://www.dartlang.org/performance/ [2] http://www.google.com/trends/explore#q=dartlang http://www.google.com/trends/explore#q=dartlang
