Just leaving this here since people will wonder the relevance of jQuery today.
> jQuery is used by 94.5% of all the websites whose JavaScript library we know. This is 77.4% of all websites.

Bootstrap does not require jQuery. Not sure if ever but not since 3.0 and were are at 5.0 at this point.
With that said, I'm quite surprised that jQuery is not abandoned, barely heard about it in the past decade or so. I suspect also that it is mostly part of boilerplate coming from other libraries and frameworks, and rarely intentional.
