Yeah, I absolutely agree that we've felt the sting of JavaScript for far too long, but the fact that it's so hard to replace only further demonstrates the point. People are optimized to expend the smallest amount of energy necessary to reach a certain point. Unless a new client-side scripting language comes out and enables something that practically everyone, even non-programmers, wants and wasn't reasonably doable before, JavaScript is here to stay.

Meanwhile, committee-designed projects like Dart have floundered and ultimately failed in their ambitions to bring a better client-side scripting language to the web, despite the backing of the largest internet company on the planet.
