Maybe not the big, funded websites. But I'm sure a lot of people doing small, static-y websites for MVPs, personal websites, or small products will use JQuery for a long time to come. JQuery is a no-brainer for anyone with small website with limited interactivity.

JQuery is like the PHP of front-end - inexpensive to build with, easy to use and loads of information available on stackoverflow.

Unfortunately I couldn't disagree more. You do not really need JQuery any more, as JS has matured. I just see it as wasted loading time.

I agree with your opinion that you do not 'need' JQuery. I'm saying that people will use it nevertheless, even if better alternatives are available.

JQuery has a lot of ergonomics that I'm really comfortable with (mainly chaining).

I agree! Though Bootstrap 4 uses jQuery for its plugins so I figured why not. BS5 will get rid of jQuery, and I plan on doing the same when updating this design system for BS5 :)

BS 5 was supposed to come out in 2020 but looks like there is a little bit of wait. A jQuery dependency is okay till then

"As of Feb 2020, jQuery is used by 74.4% of the top 10 million websites (according to W3Techs).[18]"

Get over yourself. 75% of top 10 million websites still use. Heck Wordpress and Drupal still use. It's still relevant.

I like to see new things done with jQuery. React-and-friends are too over-used right now, and it's suffocating us who want simple libs for simple sites.
