I'll agree with you that modern HTML and CSS for presentation is best-of-breed. I'll accept that the DOM API is sufficient.
But neither of those necessitate JavaScript; JS is just a language that happens to run in the browser and has DOM API bindings (and the other browser APIs too). There's no reason those identical bindings couldn't be provided in any other language.
