With a small caveat for HTML5 apps where you can install a verified version of specific code you trust in your browser or your phone. And Node.js applications which run on the server side in a controllable version.

But above is just a nuance. I agree on the basic idea when it comes to Javascript you run in the browser, it is a lost battle - unless I get a SHA256 of every version of every javascript library and compare to that, and disallow other unreadable (random emscripten junk) scripts on random pages you visit while browsing. That is why I have NoScript installed, and only allow handpicked sites to run javascript in the browser.

If only we would have had the declarative approach (I still am a little grumpy that the browser makers abandoned W3C and the far better designed declarative technology XHTML2 + XForms to pursue what is now HTML5).
