My experience has been that HTML and making changes to HTML has huge amounts of overhead all by itself.
I don't dispute that very bad javascript can cause problems, but I don't think it's the virtualization layers or the specific language that are responsible for more than a sliver of that in the vast majority of use cases.
And the pile of build and distribution tools shouldn't hurt the user at all.
