I'm asking for a single example. I can find a few, they're the sites that complain about the JS ecosystem. But my point was never that JS the theoretical feature is bad. My point was, and is; JS the thing that exists, is bad. Because nearing a total majority I've only seen JS misused.

You gave an example that I agree with, that would be a useful use of JS. Does that exist, or is that just a theoretical example? Theoretically, a lot of stuff is good. Theoretically, amphetamines could be over the counter... everyone just needs to use them responsibly!
