Google is a large company that is pushing various tech from a lot of different angles. You have the V8 team that has done a lot of great work for Javascript speeds. Members of V8 also were part of the EMCAScript committee to help move the language forward. With Google's focus on Dart, some of those V8 members have moved on to Dart. Google has also been doing a lot of work with the Shadow DOM, Polymer, and lots of other fun tech. Dart is an experiment to see if they can create a better scripting language for the web. Who knows if it'll work out, but it's nice to see a company trying something a little out there. I'm sure creating large web apps like GMail or Docs in Dart would be much more pleasurable than doing it in Javascript. For smaller scripts just to do simple form stuff, it probably won't be any better (but hopefully not worse than Javascript today).
