On Firefox with ublock, you have to hit the play button 3-4 times, but it works and there are no ads.
You should check out Google Web toolkit, totally signs like your kind of thing.
Typescript is for people who hate JavaScript, for the most part. The bulk of the people who have been writing JavaScript for years and aren’t Java converts are still using JavaScript and will continue to do so. The Java developers will continue writing Java, no matter what language they are programming in.
