Google released a new web programming language called Dart. Still remember Go? I don't know that happened there, but maybe "Dart lang" will be the new "Go lang".
The ultimate goal of Dart is to replace Javsacript; feature-wise and performance-wise. I'm still skeptical about the idea happening soon but maybe this is the future. But instead of fighting to be the best, why not just co-exist happily? I'll be happy either way.
If this language becomes mainstream, I'd want to be a part of a team or at least contribute to what they will do; which is hopefully a very good web framework inspired by Ruby on Rails or Grails.
If you're interested to discuss ideas with the Dart Team, here's a link to the Reddit discussion. Quite interestingly, read that Google has allocated significant resources on this project.
