As javascript lover I should admit that I think this is not about about javascript as language, It is more about being in right time and right place.Every one here knows javascript is awful language for optimizing and V8 kind of blow it up with every kind of optimization most of us cannot even imagine.Imagine instead of javascript , Python/Lua was standard way of browser to make dynamic content in ~2000 and web explosion days.Then I think we would talk about that language instead of javascript today.When you looking at big picture , you can see google push's Dart , which they somehow (at least I think) plan to replace javascript with Dart (I am not telling it is going to be that way , But I think this is how they have plan to do in long-term future)
