I had to write an Executive Briefing last month. Much to my own surprise, JQuery is still a major player.
JQuery dwarfs the rest according to StackOverflow Survey. A full 85% of all respondents said they use JQuery.
I always enjoyed JQuery but picked up an attitude (after reading lots of posts) that JQuery is not needed, it's on its way out etc. I think it's time for an attitude adjustment.
