Based on the numbers that I see, JavaScript is disliked more than ActionScript. When you take into account people's general dislike for anything flash related and how few people know anything about the language I think it did ok. What would be interesting would be to see a poll of the different versions of ECMAScript proposals and see what the public thinks of the real language differences between each. Classes are coming and structs are proposed and many of the things that ActionScript has had for a while are also leaking into JavaScript like rest arguments, and proxy objects. Overall I think ES6 is clearer and more flexible and I'm cool with omitting types unless you are doing things like types arrays and so on. ActionScript will go away over time and over time JavaScript environments will catch up even if they are still way behind in many respects today.
