While I'm fully supportive of making a choice to not use current trendy frameworks... putting out a jQuery-based design system in 2020 doesn't feel like it is going to find a large target audience.
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.
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 :)
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.
