I worked for ~8 years using jQuery. It was an immense step forward in the early years, but these days I find the complexity of imperative code and juggling state from multiple sources a lot worse than the ‘complexity’ of a 100-line diff & patch algorithm that lets me simply redraw the whole world from state. And in the event I need to manipulate the DOM, the native APIs are now good enough, a couple extra lines are worth not having an extra dependency - jQuery’s (and zepto and so on) utility is diminished.
