Yeah, you're right about jQuery. I got fooled because the page is loading the following URL:
> https://thebestmotherfucking.website/js/jquery-3.5.1.min.js
But the response to that request is not an actual copy of jQuery, which it seems when you just look at the URL, but the following body instead:
/* NO, really, NOBODY NEEDS TO INCLUDE A FUCKING FRAMEWORK TO MAKE A COOL WEBSITE. */
console.log("Don't worry, no jQuery was used in this website.");
var $ = function () { $.fancyRainbow = $; $.html = $; return $ }
I got fooled by it, should have verified it was actually jQuery I guess. Now the other comment about jQuery (
