Disagree strongly. I don't think looking down on JS programmers is a trend really, it's been happening for a long time now. If anything, that era has been fading with the legitimacy that runtimes like Node and adoption by high-profile companies bring to the JS ecosystem.

As for JS itself, ES6 is a great step in the right direction, and I like it a lot, though I prefer Typescript for pretty much anything when I can use it.

Also - I didn't say that you learned it first or only, just that I see a lot of praise for 'JS features' being adopted by other languages from people who very obviously don't know any better - and this only in the last 3 or so years. So I think it's a trend.
