I don't hate Java/Python/C#/C++ because I know I can realistically choose between them when building server, desktop and mobile software. I hate JavaScript because I am forced to use it for web clients. And transpilers are useless because I can't really use my high-level GUI (QT, GWT, WPF etc.) libraries. I spend enough time debugging raw JavaScript, I struggle to see how putting something on top of it will ease the pain.
That's, IMO, is another discussion. This JavaScript you talking about are written by programmers that often don't know JavaScript well and uses it as a little glue language on the client.
That's poorly written JavaScript.
On top of that, what I see missing on all this flamew.., err, discussion, is the difference between a more loose, small and open language and a more consistent, closed and regular one. Both feel a lot different. Comparing it in a given scenario may be valid, comparing they without any context at all feels like apples and oranges.
