To be fair, you could have gone through those years with an every-other approach: I know I basically did - Very late MooTools (almost none) - jQuery - Backbone - React It's not like these projects shift community blessing that quickly; it might feel like it, but these things in reality are well supported past their "peak" for at least a year or so. Your projects will still work. If you have enough of a handle on vanilla JS, these changes weren't really too obstructive. I think that's probably the most important message for the JS community here: change can be fine, good, even - but change doesn't need to happen at warpspeed.
