I really like Dart and hope it - or something like it - replaces javascript soon, but I'd heavily recommend learning javascript instead. I'll be quite some time, if ever till Dart is even 1/4 of the client side market. Even if you did learn Dart, you'd inevitably have to include external javascript libraries, so you'll have to know javascript anyway. And Google is still actively promoting javascript in things like AppScript and Angular js.
