This ideal framework would probably work in an ideal browser, without the DOM. Doug Crockford put it nicely, today's browsers are a "vast source of incompatibility, pain and misery".

Perhaps you're right, there may not be one. However, I think the point the OP is trying to make is that JavaScript is a shitty language and it would be better to invest some effort in replacing it with something better than to continuously try to "fix" all its inherent shitty-ness over and over again to little avail. Sure, JavaScript isn't as shitty today as it was 10 years ago, but it still isn't a well-thought-out, well-designed, or consistent language.

For examples of JavaScript's shitty-ness, I'd point to its various function declaration styles and their disparate effects on the code you write, its wishy-washy scoping, namespacing, the number type's precision problem, NaN being a number type, the ambiguity of this, just to name a few.

yes. well put

FWIW, there's Dart, but at the end of the day it's still just JS. This isnt to argue your point either, but one possible answer to the question(s) you bring up.
