jQuery is v4 now, but a lot of sites esp. wordpress still have 1.11 or 1.12 and only uses them to either doing modals(popover), show/hide(display), or ajax(fetch).

WordPress ships with 3.x and is already looking to update to 4

I was talking about a lot of sites in wordpress, not Wordpress themselves

If people haven't updated their sites in 10+ years, that's their problem. Has nothing to do with wordpress or jQuery
