For quick mock up / temporary pages sometimes regular JS is quite verbose, and a full framework or whatever like react/mithril/angular/ember/whatever is too much extra hassle. When writing 20 lines + 2 plugins in jQuery is enough to make a 'static site' feel much more interactive / responsive (UI, not screensize) then sometimes it works great.
It's a bit like the perl of web page JS for me. I wouldn't recommend writing a full complex application in it - although that is possible and by people who know what they're doing can be done cleanly and organised... but for super quick hackery, it's hard to beat.
